Url split query (#14211)
Addresses the following points from #14162

> - There is no built-in counterpart to url build-query for splitting a
query string

There is `from url`, which, due to naming, is a little hard to discover
and suffers from the following point

> - url parse can create records with duplicate keys
> - url parse's params should either:
>   - ~group the same keys into a list.~
> - instead of a record, be a key-value table. (table<key: string,
value: string>)

# Description

## `url split-query`

Counterpart to `url build-query`, splits a url encoded query string to
key value pairs, represented as `table<key: string, value: string>`

```
> "a=one&a=two&b=three" | url split-query
╭───┬─────┬───────╮
│ # │ key │ value │
├───┼─────┼───────┤
│ 0 │ a   │ one   │
│ 1 │ a   │ two   │
│ 2 │ b   │ three │
╰───┴─────┴───────╯
```

## `url parse`

The output's `param` field is now a table as well, mirroring the new
`url split-query`

```
> 'http://localhost?a=one&a=two&b=three' | url parse
╭──────────┬─────────────────────╮
│ scheme   │ http                │

fix $env.FILE_PWD and $env.CURRENT_FILE inside use (#14101)
# Description
Fixes: https://github.com/nushell/nushell/issues/13425

It's just a follow up to #13958.

User input can be a directory, in this case, we need to use the return
value of `find_in_dirs_env` carefully, so in case, I renamed
maybe_file_path to maybe_file_path_or_dir to emphasize it.


# User-Facing Changes
`$env.FILE_PWD` and `$env.CURRENT_FILE` will be more reliable to use.

Div, mod, and floor div overhaul (#14157)
# Description
Dividing two ints can currently return either an int or a float. Not
having a single return type for an operation between two types seems
problematic. Additionally, the type signature for division says that
dividing two ints returns only an int which does not match the current
implementation (it can also return a float). This PR changes division
between almost all types to return a float (except for `filesize /
number` or `duration / number`, since there are no float representations
for these types).

Currently, floor division between certain types is not implemented even
though the type signature allows it. Also, the current implementation of
floor division uses a combination of clamping and flooring rather than
simply performing floor division which this PR fixes. Additionally, the
signature was changed so that `int // float`, `float // int`, and `float
// float` now return float instead of int. This matches the automatic
float promotion in the rest of the operators (as well as how Python does
floor division which I think is the original inspiration).

Since regular division has always returned fractional values (and now
returns a float to reflect that), `mod` is now defined in terms of floor
division. That is, `D // d = q`, `D mod d = r`, and `D = d * q + r `.
This is just like the `%` operator in Python, which is also based off
floor division (at least for ints and floats). Additionally,
implementations missing from `mod`'s current type signature have been
added (`duration mod int` and `duration mod float`).

This PR also overhauls the overflow checking and errors for div, mod,
and floor div. If an operation overflows, it will now cause an error.

# User-Facing Changes
- Div now returns a float in most cases.
- Floor division now actually does floor division.
- Floor division now does automatic float promotion, returning a float
in more instances.
- Floor division now actually allows division with filesize and
durations as its type signature claimed.
- Mod is now defined and implemented in terms of floor division rather
than truncating division.
- Mod now actually allows filesize and durations as its type signature
claimed.
- Div, mod, and floor div now all have proper overflow checks.

## Examples

When the divisor and the dividend have the same sign, the quotient and
remainder will be the same as before. (Except that this PR will give
more accurate results, since it does not do an intermediate float
conversion). If the signs of the divisor and dividend are different,
then the results will be different, or rather actually correct.

Before:

```nu
let q = 8 // -3 # -3
let r = 8 mod -3 # 2
8 == $q * -3 + $r # false
```

After:

```nu
let q = 8 // -3 # -3
let r = 8 mod -3 # -1
8 == $q * -3 + $r # true
```


Before:

```nu
let q = -8 // 3 # -3
let r = -8 mod 3 # -2
-8 == $q * 3 + $r # false
```

After:

```nu
let q = -8 // 3 # -3
let r = -8 mod 3 # 1
-8 == $q * 3 + $r # true
```

# Tests + Formatting
Added a few tests.

Empty rest args match should be an empty list (#14246)
Fixes #14145 

# User-Facing Changes
An empty rest match would be `null` previously. Now it will be an empty
list.
This is a breaking change for any scripts relying on the old behavior.

Example script:
```nu
match [1] {
  [_ ..$rest] => {
    match $rest {
      null => { "old" }
      [] => { "new" }
    }
  } 
}
```
This expression would evaluate to "old" on current nu versions and "new"
with this patch.

Adds --no-deref flag to `touch`. Nice and backwards compatible, and I
get to touch symlinks. I still don't get to set their dates directly,
but maybe that'll come with utouch.

Some sadness in the implementation, since `set_symlink_file_times`
doesn't take Option values and we call it twice with the old "read"
values from reference (or now, if missing). This shouldn't be a big
concern since `touch` already did two calls if you set both mtime and
atime. Also, `--no-deref` applies both to the reference file, and to the
target file. No splitting them up, because that's silly.

Can always bikeshed. I nicked `--no-deref` from the uutils flag, and
made the short flag `-d` because it obviously can't be `-h`. I thought
of `-S` like in `glob`, for the "negative/filter out" uppercase short
letters. Ultimately I don't think it matters much.

Should fix #14212 since it's not really tied to uutils, besides the
comment about setting a `datetime` value directly.

$."foo.bar".baz
```

# User-Facing Changes

This PR makes the `Display` implementation for `CellPath` show a `?`
suffix on every optional entry, which makes the output consistent with
the language syntax.

Before this PR, the printing of cell paths was confusing, e.g. `$.x` and
`$.x?` were both printed as `x`. Now, the second one is printed as `x?`.

ansi name for clear-scrollback code (#14184)
Related to #14181

# Description

Our understanding of `ESC[3J` has apparently been wrong. And I say "our"
because I posted a [Super User
answer](https://superuser.com/a/1738611/1210833) a couple of years ago
with the same misconception (now fixed). In addition, the [crossterm
crate
doc](https://docs.rs/crossterm/latest/crossterm/terminal/enum.ClearType.html)
is wrong on the topic.

`ESC[3J` doesn't clear the screen plus the scrollback; it *only* clears
the scrollback. Reference the official [Xterm Control Sequences
doc](https://www.xfree86.org/4.8.0/ctlseqs.html).

> CSI P s J
> 
> Erase in Display (ED)
> 
> P s = 0 → Erase Below (default)
> P s = 1 → Erase Above
> P s = 2 → Erase All
> P s = 3 → Erase Saved Lines (xterm)

This also means that:

```nu
$"(ansi clear_entire_screen_plus_buffer)"
```

... doesn't.

This PR updates it to `ansi clear_scrollback_buffer` (short-code remains
the same).

Add metadata on open --raw with bytestreams (#14141)
# Description

This PR closes #14137 and allows the display hook to be set on byte
streams. So, with a hook like this below.
```nushell
display_output: {
    metadata access {|meta| match $meta.content_type? {
        "application/x-nuscript" | "application/x-nuon" | "text/x-nushell" => { nu-highlight },
        "application/json" => { ^bat --language=json --color=always --style=plain --paging=never },
        _ => {},
        }
    } | table
}
```
You could type `open toolkit.nu` and the text of toolkit.nu would be
highlighted by nu-highlight. This PR also changes the way content-type
is assigned with `open`. Previously it would only assign it if `--raw`
was specified.

Lastly, it changes the `is_external()` function to only say
`ByteStreamSource::Child`'s are external instead of both Child and
`ByteStreamSource::File`. Again, this was to allow the hook to function
properly. I'm not sure what negative ramifications changing
`is_external()` could have, but there may be some?

*Note that in exploring the linked issue, [other situations were
identified](https://github.com/nushell/nushell/issues/14027#issuecomment-2414602880)
which also produce inconsistent behaviour. These have knowingly been
omitted from this PR, to minimize its scope, and since they seem to have
a different cause. It's probably best to make a separate issue/PR in
which to tackle a broader scan of error handling, with a suspected
relation to streams.*

I also added an `OutDest::Print` case which might not be strictly
necessary, but is a helpful addition.

[umkdir][tests] get umask instead of assuming it (#14046)
# Description

Contributors to this projects will have a test failure if their `umask`
is not set to `0022`.

Apparently on Debian (at least on my install), it is set to `0002` which
makes my test fail. While `0022` is safer than the value I have, I want
to reduce the amount if issue new contributors could have.

I am making this test not assuming anything and instead, reading the
user umask.

# Related discussion

I see that the `umask` command implementation has been discussed in
#12256 . We could use this and enforce a umask for tests who rely on
this. I believe however (let me know what you think) that hard coded
values are harder to read in the test.

fix $env.FILE_PWD and $env.CURRENT_FILE inside use (#13958)
# Description
Fixes: #13425 

Similar to `source-env`, `use` command should also remove `FILE_PWD` and
`CURRENT_FILE` after evaluating code block in the module file.

And user input can be a directory, in this case, we need to use the
return value of `find_in_dirs_env` carefully, so in case, I renamed
`maybe_file_path` to `maybe_file_path_or_dir` to emphasize it.

# User-Facing Changes
`$env.FILE_PWD` and `$env.CURRENT_FILE` will be more reliable to use.

Rework sorting and add cell path and closure comparators to sort-by (#13154)
# Description

Closes #12535
Implements sort-by functionality of #8322
Fixes sort-by part of #8667

This PR does two main things: add a new cell path and closure parameter
to `sort-by`, and attempt to make Nushell's sorting behavior
well-defined.

## `sort-by` features

The `columns` parameter is replaced with a `comparator` parameter, which
can be a cell path or a closure. Examples are from docs PR.

1. Cell paths

The basic interactive usage of `sort-by` is the same. For example, `ls |
sort-by modified` still works the same as before. It is not quite a
drop-in replacement, see [behavior changes](#behavior-changes).
   
   Here's an example of how the cell path comparator might be useful:
   
   ```nu
   > let cities = [
{name: 'New York', info: { established: 1624, population: 18_819_000 } }
{name: 'Kyoto', info: { established: 794, population: 37_468_000 } }
{name: 'São Paulo', info: { established: 1554, population: 21_650_000 }
}
   ]
   > $cities | sort-by info.established
   ╭───┬───────────┬────────────────────────────╮
   │ # │   name    │            info            │
   ├───┼───────────┼────────────────────────────┤
   │ 0 │ Kyoto     │ ╭─────────────┬──────────╮ │
   │   │           │ │ established │ 794      │ │
   │   │           │ │ population  │ 37468000 │ │
   │   │           │ ╰─────────────┴──────────╯ │
   │ 1 │ São Paulo │ ╭─────────────┬──────────╮ │
   │   │           │ │ established │ 1554     │ │
   │   │           │ │ population  │ 21650000 │ │
   │   │           │ ╰─────────────┴──────────╯ │
   │ 2 │ New York  │ ╭─────────────┬──────────╮ │
   │   │           │ │ established │ 1624     │ │
   │   │           │ │ population  │ 18819000 │ │
   │   │           │ ╰─────────────┴──────────╯ │
   ╰───┴───────────┴────────────────────────────╯
   ```

2. Key closures

You can supply a closure which will transform each value into a sorting
key (without changing the underlying data). Here's an example of a key
closure, where we want to sort a list of assignments by their average
grade:

   ```nu
   > let assignments = [
       {name: 'Homework 1', grades: [97 89 86 92 89] }
       {name: 'Homework 2', grades: [91 100 60 82 91] }
       {name: 'Exam 1', grades: [78 88 78 53 90] }
       {name: 'Project', grades: [92 81 82 84 83] }
   ]
   > $assignments | sort-by { get grades | math avg }
   ╭───┬────────────┬───────────────────────╮
   │ # │    name    │        grades         │
   ├───┼────────────┼───────────────────────┤
   │ 0 │ Exam 1     │ [78, 88, 78, 53, 90]  │
   │ 1 │ Project    │ [92, 81, 82, 84, 83]  │
   │ 2 │ Homework 2 │ [91, 100, 60, 82, 91] │
   │ 3 │ Homework 1 │ [97, 89, 86, 92, 89]  │
   ╰───┴────────────┴───────────────────────╯
   ```

3. Custom sort closure

The `--custom`, or `-c`, flag will tell `sort-by` to interpret closures
as custom sort closures. A custom sort closure has two parameters, and
returns a boolean. The closure should return `true` if the first
parameter comes _before_ the second parameter in the sort order.
   
For a simple example, we could rewrite a cell path sort as a custom sort
(see
[here](https://github.com/nushell/nushell.github.io/pull/1568/files#diff-a7a233e66a361d8665caf3887eb71d4288000001f401670c72b95cc23a948e86R231)
for a more complex example):
   
   ```nu
   > ls | sort-by -c {|a, b| $a.size < $b.size }
   ╭───┬─────────────────────┬──────┬──────────┬────────────────╮
   │ # │        name         │ type │   size   │    modified    │

   ╰───┴─────────────────────┴──────┴──────────┴────────────────╯
   ```
   

## Making sort more consistent

I think it's important for something as essential as `sort` to have
well-defined semantics. This PR contains some changes to try to make the
behavior of `sort` and `sort-by` consistent. In addition, after working
with the internals of sorting code, I have a much deeper understanding
of all of the edge cases. Here is my attempt to try to better define
some of the semantics of sorting (if you are just interested in changes,
skip to "User-Facing changes")

- `sort`, `sort -v`, and `sort-by` now all work the same. Each
individual sort implementation has been refactored into two functions in
`sort_utils.rs`: `sort`, and `sort_by`. These can also be used in other
parts of Nushell where values need to be sorted.
  - `sort` and `sort-by` used to handle `-i` and `-n` differently.
- `sort -n` would consider all values which can't be coerced into a
string to be equal
- `sort-by -i` and `sort-by -n` would only work if all values were
strings
- In this PR, insensitive sort only affects comparison between strings,
and natural sort only applies to numbers and strings (see below).
- (not a change) Before and after this PR, `sort` and `sort-by` support
sorting mixed types. There was a lot of discussion about potentially
making `sort` and `sort-by` only work on lists of homogeneous types, but
the general consensus was that `sort` should not error just because its
input contains incompatible types.
- In order to try to make working with data containing `null` values
easier, I changed the PartialOrd order to sort `Nothing` values to the
end of a list, regardless of what other types the list contains. Before,
`null` would be sorted before `Binary`, `CellPath`, and `Custom` values.
- (not a change) When sorted, lists of mixed types will contain sorted
values of each type in order, for the most part
- (not a change) For example, `[0x[1] (date now) "a" ("yesterday" | into
datetime) "b" 0x[0]]` will be sorted as `["a", "b", a day ago, now, [0],
[1]]`, where sorted strings appear first, then sorted datetimes, etc.
- (not a change) The exception to this is `Int`s and `Float`s, which
will intermix, `Strings` and `Glob`s, which will intermix, and `None` as
described above. Additionally, natural sort will intermix strings with
ints and floats (see below).
- Natural sort no longer coerce all inputs to strings.
- I did originally make natural only apply to strings, but @fdncred
pointed out that the previous behavior also allowed you to sort numeric
strings with numbers. This seems like a useful feature if we are trying
to support sorting with mixed types, so I settled on coercing only
numbers (int, float). This can be reverted if people don't like it.
- Here is an example of this behavior in action, which is the same
before and after this PR:
      ```nushell
      $ [1 "4" 3 "2"] | sort --natural
      ╭───┬───╮
      │ 0 │ 1 │
      │ 1 │ 2 │
      │ 2 │ 3 │
      │ 3 │ 4 │
      ╰───┴───╯
      ```



# User-Facing Changes

## New features

- Replaces the `columns` string parameter of `sort-by` with a cell path
or a closure.
  - The cell path parameter works exactly as you would expect
- By default, the `closure` parameter acts as a "key sort"; that is,
each element is transformed by the closure into a sorting key
- With the `--custom` (`-c`) parameter, you can define a comparison
function for completely custom sorting order.

## Behavior changes

<details>
<summary><code>sort -v</code> does not coerce record values to
strings</summary>

This was a bit of a surprising behavior, and is now unified with the
behavior of `sort` and `sort-by`. Here's an example where you can
observe the values being implicitly coerced into strings for sorting, as
they are sorted like strings rather than numbers:

Old behavior:

```nushell
$ {foo: 9 bar: 10} | sort -v
╭─────┬────╮
│ bar │ 10 │
│ foo │ 9  │
╰─────┴────╯
```

New behavior:

```nushell
$ {foo: 9 bar: 10} | sort -v
╭─────┬────╮
│ foo │ 9  │
│ bar │ 10 │
╰─────┴────╯
```

</details>


<details>
<summary>Changed <code>sort-by</code> parameters from
<code>string</code> to <code>cell-path</code> or <code>closure</code>.
Typical interactive usage is the same as before, but if passing a
variable to <code>sort-by</code> it must be a cell path (or closure),
not a string</summary>

Old behavior:

```nushell
$ let sort = "modified"
$ ls | sort-by $sort
╭───┬──────┬──────┬──────┬────────────────╮
│ # │ name │ type │ size │    modified    │
├───┼──────┼──────┼──────┼────────────────┤
│ 0 │ foo  │ file │  0 B │ 10 hours ago   │
│ 1 │ bar  │ file │  0 B │ 35 seconds ago │
╰───┴──────┴──────┴──────┴────────────────╯
```

New behavior:

```nushell
$ let sort = "modified"
$ ls | sort-by $sort
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #10:1:14]

╰───┴──────┴──────┴──────┴───────────────╯
```
</details>

<details>
<summary>Insensitve and natural sorting behavior reworked</summary>

Previously, the `-i` and `-n` worked differently for `sort` and
`sort-by` (see "Making sort more consistent"). Here are examples of how
these options result in different sorts now:

1. `sort -n`
- Old behavior (types other than numbers, strings, dates, and binary
sorted incorrectly)
      ```nushell
      $ [2sec 1sec] | sort -n
      ╭───┬──────╮
      │ 0 │ 2sec │
      │ 1 │ 1sec │
      ╰───┴──────╯
      ```
    - New behavior
      ```nushell
      $ [2sec 1sec] | sort -n
      ╭───┬──────╮
      │ 0 │ 1sec │
      │ 1 │ 2sec │
      ╰───┴──────╯
      ```
    
2. `sort-by -i`
- Old behavior (uppercase words appear before lowercase words as they
would in a typical sort, indicating this is not actually an insensitive
sort)
     ```nushell
     $ ["BAR" "bar" "foo" 2 "FOO" 1] | wrap a | sort-by -i a
     ╭───┬─────╮
     │ # │  a  │
     ├───┼─────┤
     │ 0 │   1 │
     │ 1 │   2 │
     │ 2 │ BAR │
     │ 3 │ FOO │
     │ 4 │ bar │
     │ 5 │ foo │
     ╰───┴─────╯
     ```
- New behavior (strings are sorted stably, indicating this is an
insensitive sort)
     ```nushell
     $ ["BAR" "bar" "foo" 2 "FOO" 1] | wrap a | sort-by -i a
     ╭───┬─────╮
     │ # │  a  │
     ├───┼─────┤
     │ 0 │   1 │
     │ 1 │   2 │
     │ 2 │ BAR │
     │ 3 │ bar │
     │ 4 │ foo │
     │ 5 │ FOO │
     ╰───┴─────╯
     ```

3. `sort-by -n`
- Old behavior (natural sort does not work when data contains non-string
values)
     ```nushell
     $ ["10" 8 "9"] | wrap a | sort-by -n a
     ╭───┬────╮
     │ # │ a  │
     ├───┼────┤
     │ 0 │  8 │
     │ 1 │ 10 │
     │ 2 │ 9  │
     ╰───┴────╯
     ```
   - New behavior
     ```nushell
     $ ["10" 8 "9"] | wrap a | sort-by -n a
     ╭───┬────╮

Sorting a list of non-record values with a non-existent column/path now
errors instead of sorting the values directly (<code>sort</code> should
be used for this, not <code>sort-by</code>)
</summary>

Old behavior:

```nushell
$ [2 1] | sort-by foo
╭───┬───╮

╰───┴───╯
```

New behavior:

```nushell

  × Data cannot be accessed with a cell path
   ╭─[entry #29:1:17]

<summary><code>sort</code> and <code>sort-by</code> output
<code>List</code> instead of <code>ListStream</code> </summary>

This isn't a meaningful change (unless I misunderstand the purpose of
ListStream), since `sort` and `sort-by` both need to collect in order to
do the sorting anyway, but is user observable.

Old behavior:

```nushell

this)

fix inspect and explore panics on empty records (#13893)
# Description

Fixes a couple panics:

```
> {} | inspect
Error:   x Main thread panicked.
  |-> at crates/nu-command/src/debug/inspect_table.rs:87:15
  `-> attempt to divide by zero
```

```
> {} | explore
# see an empty column, press Down
Error:   x Main thread panicked.
  |-> at crates/nu-explore/src/views/cursor/mod.rs:39:9
  `-> attempt to subtract with overflow
```

# User-Facing Changes

`{} | inspect` now outputs an empty table:

```
╭─────────────┬────────╮
│ description │ record │
├─────────────┴────────┤
│                      │
├──────────────────────┤
```

`{} | explore` opens the help menu.

Both match the empty list behavior.

# Tests

I'm not sure how to test `explore`, as it waits for interaction.

Fix try not working with let, etc. (#13885)
# Description
Partialy addresses #13868. `try` does not catch non-zero exit code
errors from the last command in a pipeline if the result is assigned to
a variable using `let` (or `mut`).

This was fixed by adding a new `OutDest::Value` case. This is used when
the pipeline is in a "value" position. I.e., it will be collected into a
value. This ended up replacing most of the usages of `OutDest::Capture`.
So, this PR also renames `OutDest::Capture` to `OutDest::PipeSeparate`
to better fit the few remaining use cases for it.

# User-Facing Changes

fix path exists on a non-directory file (#13763)
# Description
Fixes:  #13460

The issue is caused by `try_exists` method on path, it will return
`Err(NotADirectory)` if user tried to check for a path under a regular
file.
To fix it, I think it's ok to use `exists` rather than `try_exists`,
although
[Path::exists()](https://doc.rust-lang.org/std/path/struct.Path.html#method.exists)
only checks whether or not a path was both found and readable. I think
it's ok, and we can add this information under `extra_description`.

# User-Facing Changes
The following code will no longer raise error:
```
touch a; 'a/b' | path exists
```

Fix IR for try (#13811)
# Description
Fixes a bug in the IR for `try` to match that of the regular evaluator
(continuing from #13515):
```nushell
# without IR:
try { ^false } catch { 'caught' } # == 'caught'

# with IR:
try { ^false } catch { 'caught' } # error, non-zero exit code
```

In this PR, both now evaluate to `caught`. For the implementation, I had
to add another instruction, and feel free to suggest better
alternatives. In the future, it might be possible to get rid of this
extra instruction.

# User-Facing Changes
Bug fix, `try { ^false } catch { 'caught' }` now works in IR.

Error on non-zero exit statuses (#13515)
# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```

Before this would give:
```
╭───┬──╮
│ 0 │  │
│ 1 │  │
╰───┴──╯
```

Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input

  × Eval block failed with pipeline input
   ╭─[entry #1:1:2]
 1 │ [1 2] | each { ^false }
   ·  ┬
   ·  ╰── source value
   ╰────

Error: nu:🐚:non_zero_exit_code

  × External command had a non-zero exit code
   ╭─[entry #1:1:17]
 1 │ [1 2] | each { ^false }
   ·                 ──┬──
   ·                   ╰── exited with code 1
   ╰────
```

This PR fixes #12874, fixes #5960, fixes #10856, and fixes #5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes #8569).

# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).

# Tests
Added a few tests.

# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).

Make tee work more nicely with non-collections (#13652)
# Description

This changes the behavior of `tee` to be more transparent when given a
value that isn't a list or range. Previously, anything that wasn't a
byte stream would converted to a list stream using the iterator
implementation, which led to some surprising results. Instead, now, if
the value is a string or binary, it will be treated the same way a byte
stream is, and the output of `tee` is a byte stream instead of the
original value. This is done so that we can synchronize with the other
thread on collect, and potentially capture any error produced by the
closure.

For values that can't be converted to streams, the closure is just run
with a clone of the value instead on another thread. Because we can't
wait for the other thread, there is no way to send an error back to the
original thread, so instead it's just written to stderr using
`report_error_new()`.

There are a couple of follow up edge cases I see where byte streams
aren't necessarily treated exactly the same way strings are, but this
should mostly be a good experience.

Fixes #13489.

# User-Facing Changes

Breaking change.

- `tee` now outputs and sends string/binary stream for string/binary
input.
- `tee` now outputs and sends the original value for any other input
other than lists/ranges.

encode/decode for multiple alphabets (#13428)
Based on the discussion in #13419.


## Description

Reworks the `decode`/`encode` commands by adding/changing the following
bases:

- `base32`
- `base32hex`
- `hex`
- `new-base64`

The `hex` base is compatible with the previous version of `hex` out of
the box (it only adds more flags). `base64` isn't, so the PR adds a new
version and deprecates the old one.

All commands have `string -> binary` signature for decoding and `string
| binary -> string` signature for encoding. A few `base64` encodings,
which are not a part of the
[RFC4648](https://datatracker.ietf.org/doc/html/rfc4648#section-6), have
been dropped.


## Example usage

```Nushell
~/fork/nushell> "string" | encode base32 | decode base32 | decode
string
```

```Nushell
~/fork/nushell> "ORSXG5A=" | decode base32
# `decode` always returns a binary value
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000:   74 65 73 74                                          test
```


## User-Facing Changes

- New commands: `encode/decode base32/base32hex`.
- `encode hex` gets a `--lower` flag.
- `encode/decode base64` deprecated in favor of `encode/decode
new-base64`.

Change the usage misnomer to "description" (#13598)
# Description
    
The meaning of the word usage is specific to describing how a command
function is *used* and not a synonym for general description. Usage can
be used to describe the SYNOPSIS or EXAMPLES sections of a man page
where the permitted argument combinations are shown or example *uses*
are given.
Let's not confuse people and call it what it is a description.

Our `help` command already creates its own *Usage* section based on the
available arguments and doesn't refer to the description with usage.

# User-Facing Changes

`help commands` and `scope commands` will now use `description` or
`extra_description`
`usage`-> `description`
`extra_usage` -> `extra_description`

Breaking change in the plugin protocol:

In the signature record communicated with the engine.
`usage`-> `description`
`extra_usage` -> `extra_description`

The same rename also takes place for the methods on
`SimplePluginCommand` and `PluginCommand`

Change behavior of into record on lists to be more useful (#13637)
# Description

The previous behaviour of `into record` on lists was to create a new
record with each list index as the key. This was not very useful for
creating meaningful records, though, and most people would end up using
commands like `headers` or `transpose` to turn a list of keys and values
into a record.

This PR changes that instead to do what I think the most ergonomic thing
is, and instead:

- A list of records is merged into one record.
- A list of pairs (two element lists) is folded into a record with the
first element of each pair being the key, and the second being the
value.

The former is just generally more useful than having to use `reduce`
with `merge` for such a common operation, and the latter is useful
because it means that `$a | zip $b | into record` *just works* in the
way that seems most obvious.

Example:

```nushell
[[foo bar] [baz quux]] | into record # => {foo: bar, baz: quux}
[{foo: bar} {baz: quux}] | into record # => {foo: bar, baz: quux}
[foo baz] | zip [bar quux] | into record # => {foo: bar, baz: quux}
```

The support for range input has been removed, as it would no longer
reflect the treatment of an equivalent list.

The following is equivalent to the old behavior, in case that's desired:

```
0.. | zip [a b c] | into record # => {0: a, 1: b, 2: c}
```

# User-Facing Changes
- `into record` changed as described above (breaking)
- `into record` no longer supports range input (breaking)

# Tests + Formatting
Examples changed to match, everything works. Some usage in stdlib and
`nu_plugin_nu_example` had to be changed.

Fallback to extension-based content type detection when parsing Content-Type header fails (#13610)
# Description

Previously when nushell failed to parse the content type header, it
would emit an error instead of returning the response. Now it will fall
back to `text/plain` (which, in turn, will trigger type detection based
on file extension).

May fix (potentially) nushell/nushell#11927

Supercedes: #13609 

# User-Facing Changes

It's now possible to fetch content even if the server returns an invalid

it's still better than not getting the response at all.
