Added record key renaming for derive macros IntoValue and FromValue (#13699)
# Description

Using derived `IntoValue` and `FromValue` implementations on structs
with named fields currently produce `Value::Record`s where each key is
the key of the Rust struct. For records like the `$nu` constant, that
won't work as this record uses `kebab-case` for it's keys. To accomodate
this, I upgraded the `#[nu_value(rename_all = "...")]` helper attribute
to also work on structs with named fields which will rename the keys via
the same case conversion as the enums already have.

# User-Facing Changes
Users of these macros may choose different key styles for their in
`Value` representation.

# Tests + Formatting
I added the same test suite as enums already have and updated the traits
documentation with more examples that also pass the doc test.

# After Submitting
I played around with the `$nu` constant but got stuck at the point that
these keys are kebab-cased, with this, I can play around more with it.

This issue was reported by kira in
[Discord](https://discord.com/channels/601130461678272522/1276981416307069019).
In https://github.com/nushell/nushell/pull/13311, I accidentally made it
so that custom completions are filtered according to the user's
configured completion options (`$env.config.completions`) rather than
the completion options provided as part of the custom completions. This
PR is a quick fix for that.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

It should once again be possible to override match algorithm, case
sensitivity, and substring matching (`positional`) in custom
completions.

fdncred and I discussed this in Discord a bit and we thought it might be
better to not allow custom completions to override the user's config.
However, `positional` can't currently be set inside one's config, so you
can only do strict prefix matching, no substring matching. Another PR
could do one of the following:
- Document the fact that you can provide completion options inside
custom completions
- Remove the ability to provide completion options with custom
completions and add a `$env.config.completions.positional: true` option
- Remove the ability to provide completion options with custom
completions and add a new match algorithm `substring` (this is the one I
like most, since `positional` only applies to prefix matching anyway)

Separately from these options, we could also allow completers to specify
that they don't Nushell to do any filtering and sorting on the provided
custom completions.

Fix encode/decode todo's (#13683)
Mistakes have been made. I forgot about a bunch of `todo`s in the helper
functions. So, this PR replaces them with proper errors. It also adds
tests for parse-time evaluation, because one `todo` I missed was in a
`run_const` function.

Currently the parser and the documentation generation use the signature
of the command, which means that it doesn't pick up on the changed name
of the `main` block, and therefore shows the name of the command as
"main" and doesn't find the subcommands. This PR changes the
aforementioned places to use the block signature to fix these issues.
This closes #13397. Incidentally it also causes input/output types to be
shown in the help, which is kinda pointless for scripts since they don't
operate on structured data but maybe not worth the effort to remove.

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`.

In this PR I expanded the helper attribute `#[nu_value]` on
`#[derive(FromValue)]`. It now allows the usage of `#[nu_value(type_name
= "...")]` to set a type name for the `FromValue::expected_type`
implementation. Currently it only uses the default implementation but
I'd like to change that without having to manually implement the entire
trait on my own.

I was working with byte collections like `Vec<u8>` and
[`bytes::Bytes`](https://docs.rs/bytes/1.7.1/bytes/struct.Bytes.html),
both are currently not possible to be used directly in a struct that
derives `IntoValue` and `FromValue` at the same time. The `Vec<u8>` will
convert itself into a `Value::List` but expects a `Value::String` or
`Value::Binary` to load from. I now also implemented that it can load
from `Value::List` just like the other `Vec<uX>` versions. For further
working with byte collections the type `bytes::Bytes` is wildly used,
therefore I added a implementation for it. `bytes` is already part of
the dependency graph as many crates (more than 5000 to crates.io) use
it.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
User of `nu-protocol` as library, e.g. plugin developers, can now use
byte collections more easily in their data structures and derive
`IntoValue` and `FromValue` for it.

I added a few tests that check that these byte collections are correctly

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`

Fix bugs and UB in bit shifting ops (#13663)
# Description
Fixes #11267

Shifting by a `shift >= num_bits` is undefined in the underlying
operation. Previously we also had an overflow on negative shifts for the
operators `bit-shl` and `bit-shr`
Furthermore I found a severe bug in the implementation of shifting of
`binary` data with the commands `bits shl` and `bits shr`, this
categorically produced incorrect results with shifts that were not
`shift % 4 == 0`. `bits shr` also was able to produce outputs with
different size to the input if the shift was exceeding the length of the
input data by more than a byte.

# User-Facing Changes
It is now an error trying to shift by more than the available bits with:
- `bit-shl` operator
- `bit-shr` operator
- command `bits shl`
- command `bits shr`

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.

@devyn found that https://github.com/nushell/nushell/pull/13595, which
made ranges be type-checked at parse time, introduced a bug that caused
`../foo` to be parsed as a string rather than a command call. This was
caused by `parse_range` returning a `Some` despite there being parse
errors (`/foo` doesn't match `SyntaxShape::Number`). To go back to the
old behavior, `parse_range` now returns `None` anytime there's any parse
errors met while parsing the range.

Unfortunately, this means that something like `..$foo` will be parsed as
a string if `$foo` isn't defined and as a range if it is defined. That
was the behavior before #13595, and it should probably be fixed at some
point, but I'm just trying to quickly fix the bug.

# User-Facing Changes

Prefer process name over executable path (#13618)
# Description
Prefer process name over executable path. This in practice causes the
`name` column to use just the base executable name.

Also set start_time to nothing on error, because why not.

# User-Facing Changes

Before:

> /opt/google/chrome/chrome

After:

> chrome

Also picks up changes due to `echo test-proc > /proc/$$/comm`.

# Tests + Formatting

No new coverage.

Incrementing the eager dataframe cache value before returning it (#13624)
# Description

Fixes issue [12828](https://github.com/nushell/nushell/issues/12828).

When attempting a `polars collect` on an eager dataframe, we return
dataframe as is. However, before this fix I failed to increment the
internal cache reference count. This caused the value to be dropped from
the internal cache when the references were decremented again.

This fix adds a call to cache.get to increment the value before
returning.

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

Refs:
https://discord.com/channels/601130461678272522/614593951969574961/1272895236489613366

Supercedes: #13609 

# User-Facing Changes

It's now possible to fetch content even if the server returns an invalid
content type header. Users may need to parse the response manually, but
it's still better than not getting the response at all.

# Tests + Formatting

Added a test for the new behaviour.

create a better error message for bad glob patterns (#13613)
# Description

@sholderbach pointed out that I could've made this error message better.
So, here's my attempt to make it better.

This should work. I had a hard time figuring out how to trigger the
error anyway because the type checker doesn't allow "bad" parameters to
begin with.

add more helpful error with text/xml (#13609)
# Description

This PR is meant to provide a more helpful error message when using http
get and the content type can't be parsed.

### Before

![image](https://github.com/user-attachments/assets/4e6176e2-ec35-48d8-acb3-af5d1cda4327)

### After

![image](https://github.com/user-attachments/assets/aa498ef7-f1ca-495b-8790-484593f02e35)
The span isn't perfect but there's no way to get the span of the content
type that I can see.

In the middle of fixing this error, I also discovered how to fix the
problem in general. Since you can now see the error message complaining
about double quotes (char 22 at position 0. 22 hex is `"`). The fix is
just to remove all the double quotes from the content_type and then you
get this.

### After After

![image](https://github.com/user-attachments/assets/2223d34f-4563-4dea-90eb-83326e808af1)

The discussion on Discord about this is that `--raw` or
`--ignore-errors` should eat this error and it "just work" as well as
default to text or binary when the mime parsing fails. I agree but this
PR does not implement that.

Parse time type checking for range (#13595)
# Description

As part of fixing https://github.com/nushell/nushell/issues/13586, this
PR checks the types of the operands when creating a range. Stuff like
`0..(glob .)` will be rejected at parse time. Additionally, `0..$x` will
be treated as a range and rejected if `x` is not defined, rather than
being treated as a string. A separate PR will need to be made to do
reject streams at runtime, so that stuff like `0..(open /dev/random)`
doesn't hang.

Internally, this PR adds a `ParseError::UnsupportedOperationTernary`
variant, for when you have a range like `1..2..(glob .)`.

# User-Facing Changes

Users will now receive an error if any of the operands in the ranges
they construct have types that aren't compatible with `Type::Number`.

Additionally, if a piece of code looks like a range but some parse error
is encountered while parsing it, that piece of code will still be
treated as a range and the user will be shown the parse error. This
means that a piece of code like `0..$x` will be treated as a range no
matter what. Previously, if `x` weren't the expression would've been
treated as a string `"0..$x"`. I feel like it makes the language less
complicated if we make it less context-sensitive.

Here's an example of the error you get:
```

Note: I made the operands themselves (above, `(glob .)`) be garbage,
rather than the `..` operator itself. This doesn't match the behavior of
the math operators (if you do `1 + "foo"`, `+` gets highlighted red).
This is because with ranges, the range operators aren't `Expression`s
themselves, so they can't be turned into garbage. I felt like here, it
makes more sense to highlight the individual operand anyway.

support SyntaxShape::OneOf in named args (#13553)
# Description
Fixes: #13253

The issue is because nushell use `parse_value` to parse named args, but
`parse_value` doesn't parse `OneOf` syntax shape.

# User-Facing Changes
`OneOf` in named args should works again.

# Tests + Formatting
I think it's hard to add a test, because nushell doesn't support `oneof`
syntax in custom command yet.

Replace only leading home path with ~ in the title (#13600)
# Description :
- This pull request addresses issue #13594 where any substring of the
path that matches the home directory is replaced with `~` in the title
bar. This was problematic because partial matches within the path were
also being replaced.

Make error-message more helpful when user invokes a non-executable file (#13589)
# Description

Fixes Issue #13477 
This adds a check to see if a user is trying to invoke a
(non-executable) file as a command and returns a helpful error if so.
EDIT: this will not work on Windows, and is arguably not relevant there,
because of the different semantics of executables. I think the
equivalent on Windows would be if a user tries to invoke `./foo`, we
should look for `foo.exe` or `foo.bat` in the directory and recommend
that if it exists.

# User-Facing Changes

When a user invokes an unrecognized command that is the path to an
existing file, the error used to say:
`{name} is neither a Nushell built-in or a known external command` 
This PR proposes to change the message to:
`{name} refers to a file that is not executable. Did you forget to to
set execute permissions?`

# Tests + Formatting
Ran cargo fmt, clippy and test on the workspace. 
EDIT: added test asserting the new behavior

Add --raw switch to print for binary data (#13597)
# Description

Something I meant to add a long time ago. We currently don't have a
convenient way to print raw binary data intentionally. You can pipe it
through `cat` to turn it into an unknown stream, or write it to a file
and read it again, but we can't really just e.g. generate msgpack and
write it to stdout without this. For example:

```nushell
[abc def] | to msgpack | print --raw
```

This is useful for nushell scripts that will be piped into something
else. It also means that `nu_plugin_nu_example` probably doesn't need to
do this anymore, but I haven't adjusted it yet:

```nushell
def tell_nushell_encoding [] {
  print -n "\u{0004}json"
}
```

This happens to work because 0x04 is a valid UTF-8 character, but it
wouldn't be possible if it were something above 0x80.

`--raw` also formats other things without `table`, I figured the two
things kind of go together. The output is kind of like `to text`.
Debatable whether that should share the same flag, but it was easier
that way and seemed reasonable.

# User-Facing Changes
- `print` new flag: `--raw`

# Tests + Formatting
Added tests.

Add parse error for external commands used in assignment without caret (#13585)
# Description

As per our Wednesday meeting, this adds a parse error when something
that would be parsed as an external call is present at the top level,
unless the head of the external call begins with a caret (to make it
explicit).

I tried to make the error quite descriptive about what should be done.

# User-Facing Changes
These now cause a parse error:

```nushell
$foo = bar
$foo = `bar`
```

These would have been interpreted as strings before this version, but
now they'd be interpreted as external calls. This behavior is consistent
with `let`/`mut` (which is unaffected by this change).

Here is an example of the error:

```
Error:   × External command calls must be explicit in assignments
   ╭─[entry #3:1:8]
 1 │ $foo = bar
   ·        ─┬─
   ·         ╰── add a caret (^) before the command name if you intended to run and capture its output
   ╰────
  help: the parsing of assignments was changed in 0.97.0, and this would have previously been treated as a string.
        Alternatively, quote the string with single or double quotes to avoid it being interpreted as a command name. This
        restriction may be removed in a future release.
```

# Tests + Formatting

Tests added to cover the change. Note made about it being temporary.

Clean up key event handling (#13574)
# Description
Cleanups:
 - Add "key_press" to event reading function names to match reality
- Move the relevant comment about why only key press events are
interesting one layer up
 - Remove code duplication in handle_events
- Make `try_next` try harder (instead of bail on a boring event); I
think that was the original intention
- Remove recursion from `next` (I think that's clearer? but maybe just
what I'm used to)

# User-Facing Changes
None

# Tests + Formatting
This cleans up existing code, no new test coverage.

Merge polars sink and polars to-* to polars save (#13568)
# Description
This pull request merges `polars sink` and `polars to-*` into one
command `polars save`.


# User-Facing Changes
- `polars to-*` commands have all been replaced with `polars save`. When
saving a lazy frame to a type that supports a polars sink operation, a
sink operation will be performed. Sink operations are much more
performant, performing a collect while streaming to the file system.

Bump typo with new ignore (#13563)

(not sure how to narrow the word ignore to a file, maybe the better
course of action would be to mark this file as an ignore with all the

Make the math commands const (#13566)
This PR closes [Issue
#13482](https://github.com/nushell/nushell/issues/13482)

# Description
This PR tend to make all math function to be constant. 

# User-Facing Changes
The math commands now can be used as constant methods.

### Some Example
```
> const MODE = [3 3 9 12 12 15] | math mode
> $MODE
╭───┬────╮
│ 0 │  3 │
│ 1 │ 12 │
╰───┴────╯

> const LOG = [16 8 4] | math log 2
> $LOG
╭───┬──────╮
│ 0 │ 4.00 │
│ 1 │ 3.00 │
│ 2 │ 2.00 │
╰───┴──────╯

> const VAR = [1 3 5] | math variance
> $VAR
2.6666666666666665
```

# Tests + Formatting
Tests are added for all of the math command to test there constant
behavior.

I mostly focused on the actual user experience, not the correctness of
the methods and algorithms.

# After Submitting
I think this change don't require any additional documentation. Feel
free to correct me in this topic please.
