Fix memory consumption of into sqlite (#10232)
# Description

Currently, the `into sqlite` command collects the entire input stream
into a single Value, which soaks up the entire input into memory, before
it ever tries to write anything to the DB. This is very problematic for
large inputs; for example, I tried transforming a multi-gigabyte CSV
file into SQLite, and before I knew what was happening, my system's
memory was completely exhausted, and I had to hard reboot to recover.

This PR fixes this problem by working directly with the pipeline stream,
inserting into the DB as values are read from the stream.

In order to facilitate working with the stream directly, I introduced a
new `Table` struct to store the connection and a few configuration
parameters, as well as to make it easier to lazily create the table on
the first read value.

In addition to the purely functional fixes, a few other changes were
made to the serialization and user facing behavior.

### Serialization

Much of the preexisting code was focused on generating the exact text
needed for a SQL statement. This is unneeded and less safe than using
the `rusqlite` crate's serialization for native Rust types along with
prepared statements.

### User-Facing Changes

Currently, the command is very liberal in the input types it accepts.
The strategy is basically if it is a record, try to follow its structure
and make an analogous SQL row, which is pretty reasonable. However, when
it's not a record, it basically tries to guess what the user wanted and
just makes a single column table and serializes the value into that one
column, whatever type it may be.

This has been changed so that it only accepts records as input. If the
user wants to serialize non-record types into SQL, then they must
explicitly opt into doing this by constructing a record or table with it
first. For a utility for inserting data into SQL, I think it makes more
sense to let the user choose how to convert their data, rather than make
a choice for them that may surprise them.

However, I understand this may be a controversial change. If the
maintainers don't agree, I can change this back.

#### Long switch names

The `file_name` and `table_name` long form switches are currently
snake_case and expect to be as such at the command line. These have been
changed to kebab-case to be more conventional.

# Tests + Formatting

To test the memory consumption, I used [this publicly available index of
all Wikipedia articles](https://dumps.wikimedia.org/enwiki/20230820/),
using the first 10,000, 100,000, and 1,000,000 entries, in that order. I
ran the following script to benchmark the changes against the current
stable release:

```nu
#!/usr/bin/nu

# let shellbin = $"($env.HOME)/src/nushell/target/aarch64-linux-android/release/nu"
let shellbin = "nu"
const dbpath = 'enwiki-index.db'

[10000, 100000, 1000000]
  | each {|rows|
      rm -f $dbpath;
      do { time -f '%M %e %U %S' $shellbin -c (
        $"bzip2 -cdk ~/enwiki-20230820-pages-articles-multistream-index.txt.bz2
            | head -n ($rows)
            | lines
            | parse '{offset}:{id}:{title}'
            | update cells -c [offset, id] { into int }
            | into sqlite ($dbpath)"
        )
      }
      | complete
      | get stderr
      | str trim
      | parse '{rss_max} {real} {user} {kernel}'
      | update cells -c [rss_max] { $"($in)kb" | into filesize }
      | update cells -c [real, user, kernel] { $"($in)sec" | into duration }
      | insert rows $rows
      | roll right
    }
  | flatten
  | to nuon
```

This yields the following results

Current stable release:

|rows|rss_max|real|user|kernel|
|-|-|-|-|-|
|10000|53.6 MiB|770ms|460ms|420ms|

|1000000|1.7 GiB|1min 8sec 810ms|38sec 690ms|42sec 550ms|

# Note

I started this branch kind of at the same time as my others, but I
understand the feedback that smaller PRs are preferred. Let me know if
it would be better to split this up.

I do think the scope of the changes are on the bigger side even without
the behavior changes I mentioned, so I'm not sure if that will help this
particular PR very much, but I'm happy to oblige on request.

check existance w/o traversing symlinks (#10872)
# Description

Currently `path exists` checks the file/folder's existence by traversing
symlinks. I've added a `-n` switch/flag that disables symlink
traversing, similar to what `path expand -n` does.

## The Long Story (for those interested)

Hello! 👋 While working on one of my scripts, I discovered that the `path
exists` command was traversing symlinks. This meant that even if the
file existed, it would fail if the pointed location didn't exist. To
address this, I've introduced a new `-n` flag, which I borrowed from the
`path expand` command. This addition should make the behavior more
consistent within the *path commands universe*.

## But, is it any useful?
 
```nushell
let compat = /run/media/userX/DriveX/steam/steamapps/compatdata
if "symlink" == ($compat | path expand -n | path type) {}
# to this
if ($compat | path exists -n) {}
```

# User-Facing Changes

Users, will not efect. Unless they use the mentioned `-n` flag/switch.

Add file attribute handling flag to cp (#11491)
# Description
This PR adds possibility to preserve/strip attributes from files when
using `cp` (via uu_cp::Attributes). To achieve this a single `--preserve
<list of attributes>` flag is added. This is different from how
coreutils and uutils cp function, but I believe this is better for
nushell.

Coreutils cp has three options `-p`, `--preserve` and `--no-presevce`.
The logic of these two options is not straightforward. As far as I
understand it is:
1. By default only mode attributes are preserved
2. `--preserve` option adds to default preserved attributes specified
ones (e.g. `--preserve=xattr,timestamps` will preserve mode, timestamps
and xattr)
3. `-p` is the same as `--preserve=mode,ownership,timestamps`
4. `--no-preserve` option rejects specified attributes (having priority
over `--preserve`)

However (in my opinion) the `--no-preserve` option is not needed,
because its only use seems to be rejecting attributes preserved by
default. But there is no need for this in nushell, because `--preserve`
can be specified with empty list as argument (whereas coreutils cp will
display a `cp: ambiguous argument ‘’ for ‘--preserve’` error if
`--preserve` is used with empty string as argument).

So to simplify this command is suggest (and implemented) only the
`--preserve` with the following logic:
1. By default mode attribute is preserved (as in coreutils cp)
2. `--preserve [ ... ]` will overwrite default with whatever is
specified in list (empty list meaning preserve nothing)

This way cp without `--preserve` behaves the same as coreutils `cp`, but
instead of using combinations of `--preserve` and `--no-preserve` one
needs to use `--preserve [ ... ]` with all attributes specified
explicitly. This seems more user-friendly to me as it does not require
remembering what the attributes preserved by default are and rejecting
them manually. However I see the possible problem with behavior
different from coreutils implementation, so some feedback is
apprecieated!

# User-Facing Changes
Users can now preserve or reject file attributes when using `cp`

# Tests + Formatting
Added tests manipulating mode and timestamps attributes.

Fix incorrect handling of boolean flags for builtin commands (#11492)
# Description
Possible fix of #11456
This PR fixes a bug where builtin commands did not respect the logic of
dynamically passed boolean flags. The reason is
[has_flag](6f59abaf43/crates/nu-protocol/src/ast/call.rs (L204C5-L212C6))
method did not evaluate and take into consideration expression used with
flag.

To address this issue a solution is proposed:
1. `has_flag` method is moved to `CallExt` and new logic to evaluate
expression and check if it is a boolean value is added
2. `has_flag_const` method is added to `CallExt` which is a constant
version of `has_flag`
3. `has_named` method is added to `Call` which is basically the old
logic of `has_flag`
4. All usages of `has_flag` in code are updated, mostly to pass
`engine_state` and `stack` to new `has_flag`. In `run_const` commands it
is replaced with `has_flag_const`. And in a few select places: parser,
`to nuon` and `into string` old logic via `has_named` is used.

# User-Facing Changes
Explicit values of boolean flags are now respected in builtin commands.

Refactor tests (using cococo instead of ^echo) (#11479)
- related PR: #11478 

# Description

Now we can use `nu --testbin cococo` instead of `^echo` to echo messages
to stdout in tests.

But `nu` treats parameters as its own flags when parameter starts with
`-`. So `^echo --foo='bar'` still use `^echo`.

Finishes implementing https://github.com/nushell/nushell/issues/10598,
which asks for a spread operator in lists, in records, and when calling
commands.

This PR will allow spreading arguments to commands (both internal and
external). It will also deprecate spreading arguments automatically when
passing to external commands.

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

- Users will be able to use `...` to spread arguments to custom/builtin
commands that have rest parameters or allow unknown arguments, or to any
external command
- If a custom command doesn't have a rest parameter and it doesn't allow
unknown arguments either, the spread operator will not be allowed
- Passing lists to external commands without `...` will work for now but
will cause a deprecation warning saying that it'll stop working in 0.91
(is 2 versions enough time?)

Here's a function to help with demonstrating some behavior:
```nushell
> def foo [ a, b, c?, d?, ...rest ] { [$a $b $c $d $rest] | to nuon }
```

You can pass a list of arguments to fill in the `rest` parameter using
`...`:
```nushell
> foo 1 2 3 4 ...[5 6]
[1, 2, 3, 4, [5, 6]]
```

If you don't use `...`, the list `[5 6]` will be treated as a single
argument:

```nushell
> foo 1 2 3 4 [5 6] # Note the double [[]]
[1, 2, 3, 4, [[5, 6]]]
```

You can omit optional parameters before the spread arguments:
```nushell
> foo 1 2 3 ...[4 5] # d is omitted here
[1, 2, 3, null, [4, 5]]
```

If you have multiple lists, you can spread them all:
```nushell
> foo 1 2 3 ...[4 5] 6 7 ...[8] ...[]
[1, 2, 3, null, [4, 5, 6, 7, 8]]
```

Here's the kind of error you get when you try to spread arguments to a
command with no rest parameter:

![image](https://github.com/nushell/nushell/assets/45539777/93faceae-00eb-4e59-ac3f-17f98436e6e4)

And this is the warning you get when you pass a list to an external now
(without `...`):

- Spreading a list literal containing arguments of the wrong type (parse
error)
- Spreading a non-list value, both to internal and external commands
- Having named arguments in the middle of rest arguments

# Examples

Suppose you have multiple tables:
```nushell
let people = [[id name age]; [0 alice 100] [1 bob 200] [2 eve 300]]
let evil_twins = [[id name age]; [0 ecila 100] [-1 bob 200] [-2 eve 300]]
```

Maybe you often find yourself needing to merge multiple tables and want
a utility to do that. You could write a function like this:
```nushell
def merge_all [ ...tables ] { $tables | reduce { |it, acc| $acc | merge $it } }
```

Then you can use it like this:
```nushell
> merge_all ...([$people $evil_twins] | each { |$it| $it | select name age })
╭───┬───────┬─────╮
│ # │ name  │ age │
├───┼───────┼─────┤
│ 0 │ ecila │ 100 │
│ 1 │ bob   │ 200 │
│ 2 │ eve   │ 300 │
╰───┴───────┴─────╯
```

Except they had duplicate columns, so now you first want to suffix every
column with a number to tell you which table the column came from. You
can make a command for that:
```nushell
def select_and_merge [ --cols: list<string>, ...tables ] {
  let renamed_tables = $tables
    | enumerate
    | each { |it|
      $it.item | select $cols | rename ...($cols | each { |col| $col + ($it.index | into string) })
    };
  merge_all ...$renamed_tables
}
```
And call it like this:
```nushell
> select_and_merge --cols [name age] $people $evil_twins
╭───┬───────┬──────┬───────┬──────╮
│ # │ name0 │ age0 │ name1 │ age1 │
├───┼───────┼──────┼───────┼──────┤
│ 0 │ alice │  100 │ ecila │  100 │
│ 1 │ bob   │  200 │ bob   │  200 │
│ 2 │ eve   │  300 │ eve   │  300 │
╰───┴───────┴──────┴───────┴──────╯
```

---

Suppose someone's made a command to search for APT packages:

```nushell
# The main command
def search-pkgs [
    --install                   # Whether to install any packages it finds
    log_level: int              # Pretend it's a good idea to make this a required positional parameter
    exclude?: list<string>      # Packages to exclude
    repositories?: list<string> # Which repositories to look in (searches in all if not given)
    ...pkgs                     # Package names to search for
] {
  { install: $install, log_level: $log_level, exclude: ($exclude | to nuon), repositories: ($repositories | to nuon), pkgs: ($pkgs | to nuon) }
}
```

It has a lot of parameters to configure it, so you might make your own
helper commands to wrap around it for specific cases. Here's one
example:
```nushell
# Only look for packages locally
def search-pkgs-local [
    --install              # Whether to install any packages it finds
    log_level: int
    exclude?: list<string> # Packages to exclude
    ...pkgs                # Package names to search for
] {
  # All required and optional positional parameters are given
  search-pkgs --install=$install $log_level [] ["<local URI or something>"] ...$pkgs
}
```
And you can run it like this:
```nushell
> search-pkgs-local --install=false 5 ...["python2.7" "vim"]
╭──────────────┬──────────────────────────────╮
│ install      │ false                        │
│ log_level    │ 5                            │
│ exclude      │ []                           │
│ repositories │ ["<local URI or something>"] │
│ pkgs         │ ["python2.7", vim]           │
╰──────────────┴──────────────────────────────╯
```

One thing I realized when writing this was that if we decide to not
allow passing optional arguments using the spread operator, then you can
(mis?)use the spread operator to skip optional parameters. Here, I
didn't want to give `exclude` explicitly, so I used a spread operator to
pass the packages to install. Without it, I would've needed to do
`search-pkgs-local --install=false 5 [] "python2.7" "vim"` (explicitly
pass `[]` (or `null`, in the general case) to `exclude`). There are
probably more idiomatic ways to do this, but I just thought it was
something interesting.

If you're a virologist of the [xkcd](https://xkcd.com/350/) kind,
another helper command you might make is this:
```nushell
# Install any packages it finds
def live-dangerously [ ...pkgs ] {
  # One optional argument was given (exclude), while another was not (repositories)
  search-pkgs 0 [] ...$pkgs --install # Flags can go after spread arguments
}
```

Running it:
```nushell
> live-dangerously "git" "*vi*" # *vi* because I don't feel like typing out vim and neovim
╭──────────────┬─────────────╮
│ install      │ true        │
│ log_level    │ 0           │
│ exclude      │ []          │
│ repositories │ null        │
│ pkgs         │ [git, *vi*] │
╰──────────────┴─────────────╯
```

Here's an example that uses the spread operator more than once within
the same command call:

Allow http commands' automatic redirect-following to be disabled (#11329)
Intends to close #8920 

This PR suggests a new flag for the `http` commands, `--redirect-mode`,
which enables users to choose between different redirect handling modes.
The current behaviour of letting ureq silently follow redirects remains
the default, but two new options are introduced here, following the lead
of [JavaScript's `fetch`
API](https://developer.mozilla.org/en-US/docs/Web/API/fetch#redirect):
"manual", where any 3xx response to a request is simply returned as the
command's result, and "error", where any 3xx response causes a network
error like those caused by 4xx and 5xx responses.

This PR is a draft. Tests have not been added or run, the flag is
currently only implemented for the `http get` command, and design tweaks
are likely to be appropriate.

Most notably, it's not obvious to me whether a single flag which can
take one of three values is the nicest solution here.
We might instead consider two binary flags (like
`--no-following-redirects` and `--disallow-redirects`, although I'm bad
at naming things so I need help with that anyway), or completely drop
the "error" option if it's not deemed useful enough. (I personally think
it has some merit, especially since 4xx and 5xx responses are already
treated as errors by default; So this would allow users to treat only
immediate 2xx responses as success)

# User-facing changes
New options for the `http [method]` commands. Behaviour remains
unchanged when the command line flag introduced here is not used.

Fix sandboxing of redirection tests (#11407)
When running `cargo test --workspace` a file `crates/nu-command/a.txt`
remained which we also saw as an accidential additions in some commits.

Searching for `a.txt` narrowed it down that
`redirection_keep_exit_codes` was not sandboxed in a temporary directory
and created this file.

Went through redirection tests and placed them in a `Playground` to get
sandboxing `dirs` for `nu!(cwd:`.
For those tests where redirection fails and no file should be created
now I added a check that no file is created on accident.


- Sandbox `redirection_keep_exit_codes` test
- Sandbox `no_duplicate_redirection` test
- Check that no redirect file is created on error
- Sandbox `redirection_should_have_a_target` test

installed.

There were only two minor tests which required a change.

Fix replacement closures for update, insert, and upsert (#11258)
# Description
This PR addresses #11204 which points out that using a closure for the
replacement value with `update`, `insert`, or `upsert` does not work for
lists.

# User-Facing Changes
- Replacement closures should now work for lists in `upsert`, `insert`,
and `update`. E.g., `[0] | update 0 {|i| $i + 1 }` now gives `[1]`
instead of an unhelpful error.
- `[1 2] | insert 4 20` no longer works. Before, this would give `[1, 2,
null, null, 20]`, but now it gives an error. This was done to match the
intended behavior in `Value::insert_data_at_cell_path`, whereas the
behavior before was probably unintentional. Following
`Value::insert_data_at_cell_path`, inserting at the end of a list is
also fine, so the valid indices for `upsert` and `insert` are
`0..=length` just like `Vec::insert` or list inserts in other languages.

# Tests + Formatting
Added tests for `upsert`, `insert`, and `update`:
- Replacement closures for lists, list streams, records, and tables
- Other list stream tests

Match ++= capabilities with ++ (#11130)
Allow `++=` to work in all situations `++` does, namely for appending
single elements: `$list ++= 1`.

Resolve #11087

# Description

Bring `++=` to parity with `++`.

# User-Facing Changes

It is now possible to do `$list ++= 1` (appending a single element).
Similarly, this can be done:

```Nushell

~> $a ++= 2
~> a
╭───┬───╮

When using redirection, if a command generates non-zero exit code, the script should stop running (#11191)
# Description
Fixes: #11153

To make sure scripts stop from running on non-zero exit code, we need to
invoke `might_consume_external_result` on
`PipelineData::ExternalStream`, so it can tell nushell if this command
exists with non-zero exit code.

And this pr also adjusts some test cases.

# User-Facing Changes
```nushell
^false out> /dev/null; print "ok"
```

After this pr, it shouldn't print ok.

Support o>>, e>>, o+e>> to append output to an external file (#10764)
# Description

Cp target expansion (#11152)
# Description
This PR addresses issue with cp brough up on
[discord](https://discord.com/channels/601130461678272522/614593951969574961/1177669443917189130)
where target of cp is not correctly expanded.
If one has directory `test` with file `file.txt` in it then the
following command (in one line or inside a `do` block):
```nu
cd test; let file = 'copy.txt'; cp file.txt $file
```
will create a `copy.txt` in `.` not in `test` instead. This happens
because target of `cp` is a variable which is not expanded unlike a
string literal

# User-Facing Changes
`cp` will correctly parse realative target paths

Redirect: support redirect stderr with piping stdout to next commands. (#10851)
# Description
Fixes: #10271

Given the following script:
```shell
# test.sh
echo aaaaa
echo bbbbb 1>&2
echo cc
```

This pr makes the following command possible:
```nushell
bash test.sh err> /dev/null | lines | each {|line| $line | str length}
```


## General idea behind the change:
When nushell redirect stderr message to external file
1. it take stdout of external stream, and pass this stream to next
command, so it won't block next pipeline command from running.
2. relative stderr stream are handled by `save` command

These two streams are handled separately, so we need to delegate a
thread to `save` command, or else we'll have a chance to hang nushell,
we have meet a similar before: #5625.

### One case to consider
What if we're failed to save to an external stream? (Like we don't have
a permission to save to a file)?
In this case nushell will just print a waning message, and don't stop
the following scripts from running.

# User-Facing Changes
## Before
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
aaaaa
cc
```

## After
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
╭───┬───╮
│ 0 │ 5 │
│ 1 │ 2 │
╰───┴───╯
```

BTY, after this pr, the following commands are impossible either, it's
important to make sure that the implementation doesn't introduce too
much costs:
```nushell
❯ echo a e> a.txt e> a.txt
Error:   × Can't make stderr redirection twice
   ╭─[entry #1:1:1]
 1 │ echo a e> a.txt e> a.txt
   ·                 ─┬
   ·                  ╰── try to remove one

Add is-terminal to determine if stdin/out/err are a terminal (#10970)
# Description

I'm not sure if "is-terminal" is the best name for this command as there
is also "term size". Uses
[`is_terminal()`](https://doc.rust-lang.org/stable/std/io/trait.IsTerminal.html#tymethod.is_terminal)
which is cross-platform.

Possible alternative names:
* `term is-tty --stdout`
* `term is-tty stdout`
* `term is-terminal stdout`

If multiple streams are provided an error is returned. The error span
covers all arguments as the incompatible one is not known. This may be
new?

Fixes #10517

# User-Facing Changes

* Add `is-terminal` to check if stdin, stdout, or stderr are a terminal
(TTY)

# Tests + Formatting

The nu tests always redirect stdin, stdout, and stderr so a positive
test case is not possible without extra work

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

The new command will be added automatically

Refactor Value cell path functions to fix bugs (#11066)
# Description
Slightly refactors the cell path functions (`insert_data_at_cell_path`,
etc.) for `Value` to fix a few bugs and ensure consistent behavior.
Namely, case (in)sensitivity now applies to lazy records just like it
does for regular `Records`. Also, the insert behavior of `insert` and
`upsert` now match, alongside fixing a few related bugs described below.
Otherwise, a few places were changed to use the `Record` API.

# Tests
Added tests for two bugs:
- `{a: {}} | insert a.b.c 0`: before this PR, doesn't create the
innermost record `c`.
- `{table: [[col]; [{a: 1}], [{a: 1}]]} | insert table.col.b 2`: before
this PR, doesn't add the field `b: 2` to each row.

Add mktemp command (#11005)
closes #10845 

I've opened this a little prematurely to get some questions answered
before I cleanup the code.

As I started trying to better understand GNUs `mktemp` I've realized its
kind of peculiar and we might want to change its behavior to introduce
it to nushell.

#### quiet and dry run

Does it make sense to keep the `quiet` and `dry_run` flags? I don't
think so. The GNU documentation says this about the dry run flag "Using
the output of this command to create a new file is inherently unsafe, as
there is a window of time between generating the name and using it where
another process can create an object by the same name." So yeah why keep
it? As far as quiet goes, does it make sense to silence the errors in
nushell?

#### other confusing flags

According to the [gnu
docs](https://www.gnu.org/software/coreutils/manual/html_node/mktemp-invocation.html),
the `-t` flag is deprecated and the `-p`/ `--tempdir` are the same flag
with the only difference being `--tempdir` takes an optional path, Given
that, I've broken the `-p` away from `--tempdir`. Now there is one
switch `--tmpdir`/`-t` and one named param `--tmpdir-path`/`-p`.

GNU mktemp
```
  -p DIR, --tmpdir[=DIR]  interpret TEMPLATE relative to DIR; if DIR is not
                        specified, use $TMPDIR if set, else /tmp.  With
                        this option, TEMPLATE must not be an absolute name;
                        unlike with -t, TEMPLATE may contain slashes, but
                        mktemp creates only the final component
  -t                  interpret TEMPLATE as a single file name component,
                        relative to a directory: $TMPDIR, if set; else the
                        directory specified via -p; else /tmp [deprecated]

```
to
nushell mktemp
```
  -p, --tmpdir-path <Filepath> # named param, must provide a path
  -t, --tmpdir                 # a switch
```

Is this a terrible idea?

What should I do?

Refactor drop columns to fix issues (#10903)
# Description
This PR refactors `drop columns` and fixes issues #10902 and #6846.
Tables with "holes" are now handled consistently, although still
somewhat awkwardly. That is, the columns in the first row are used to
determine which columns to drop, meaning that the columns displayed all
the way to the right by `table` may not be the columns actually being
dropped. For example, `[{a: 1}, {b: 2}] | drop column` will drop column
`a` instead of `b`. Before, this would give a list of empty records.

# User-Facing Changes
`drop columns` can now take records as input.

Add exec command for Windows (#11001)
# Description
Based of the work and discussion in #10844, this PR adds the `exec`
command for Windows. This is done by simply spawning a
`std::process::Command` and then immediately exiting via
`std::process::exit` once the child process is finished. The child
process's exit code is passed to `exit`.

# User-Facing Changes
The `exec` command is now available on Windows, and there should be no
change in behaviour for Unix systems.

Update description and error types for split-by (#10865)
# Description

`split-by` only works on a `Record`, the error type was updated to
match, and now uses a more-specific type. (Two type fixes for the price
of one!)

The `usage` was updated to say "record" as well

# User-Facing Changes

* Providing the wrong type to `split-by` now gives an error messages
with the correct required input type

Previously:

```
❯ ls | get name | split-by type
Error:   × unsupported input
   ╭─[entry #267:1:1]
 1 │ ls | get name | split-by type
   ·      ─┬─
   ·       ╰── requires a table with one row for splitting
   ╰────
```

With this PR:

```
❯ ls | get name | split-by type
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #1:1:1]
 1 │ ls | get name | split-by type
   ·      ─┬─
   ·       ╰── requires a record to split
   ╰────
```

Refactor error make (#10923)
- Replaced `start`/`end` with span.
- Fixed standard library.
- Add `help` option.
- Add a couple more errors for invalid record types.

Resolve #10914


# Description



# User-Facing Changes

- **BREAKING CHANGE:** `error make` now takes in `span` instead of
`start`/`end`:

  ```Nushell
  error make {
      msg: "Message"
      label: {
          text: "Label text"
          span: (metadata $var).span
      }
  }
  ```
- `error make` now has a `help` argument for custom error help.

Disallow duplicated columns in table literals (#10875)
# Description
Pretty much all operations/commands in Nushell assume that the column
names/keys in a record and thus also in a table (which consists of a
list of records) are unique.
Access through a string-like cell path should refer to a single column
or key/value pair and our output through `table` will only show the last
mention of a repeated column name.

```nu
[[a a]; [1 2]]
╭─#─┬─a─╮
│ 0 │ 2 │
╰───┴───╯
```

While the record parsing already either errors with the
`ShellError::ColumnDefinedTwice` or silently overwrites the first
occurence with the second occurence, the table literal syntax `[[header
columns]; [val1 val2]]` currently still allowed the creation of tables
(and internally records with more than one entry with the same name.

This is not only confusing, but also breaks some assumptions around how
we can efficiently perform operations or in the past lead to outright
bugs (e.g. #8431 fixed by #8446).

This PR proposes to make this an error.
After this change another hole which allowed the construction of records
with non-unique column names will be plugged.

## Parts
- Fix `SE::ColumnDefinedTwice` error code
- Remove previous tests permitting duplicate columns
- Deny duplicate column in table literal eval
- Deny duplicate column in const eval
- Deny duplicate column in `from nuon`

# User-Facing Changes
`[[a a]; [1 2]]` will now return an error:

```
Error: nu:🐚:column_defined_twice

  × Record field or table column used twice
   ╭─[entry #2:1:1]
 1 │ [[a a]; [1 2]]
   ·   ┬ ┬
   ·   │ ╰── field redefined here
   ·   ╰── field first defined here
   ╰────
```

this may under rare circumstances block code from evaluating.

Furthermore this makes some NUON files invalid if they previously
contained tables with repeated column names.

# Tests + Formatting
Added tests for each of the different evaluation paths that materialize
tables.

use to_lowercase in str downcase (#10850)
# Description
as we can see in the [documentation of
`str.to_lowercase`](https://doc.rust-lang.org/std/primitive.str.html#method.to_lowercase),
not only ASCII symbols have lower and upper variants.

- `str upcase` uses the correct method to convert the string

7ac5a01e2f/crates/nu-command/src/strings/str_/case/upcase.rs (L93)
- `str downcase` incorrectly converts only ASCII characters

7ac5a01e2f/crates/nu-command/src/strings/str_/case/downcase.rs (L124)

this PR uses `str.to_lower_case` instead of `str.to_ascii_lowercase` in
`str downcase`.

# User-Facing Changes
- upcase still works fine
```nushell
~ l> "ὀδυσσεύς" | str upcase
ὈΔΥΣΣΕΎΣ
```
- downcase now works

👉 before
```nushell
~ l> "ὈΔΥΣΣΕΎΣ" | str downcase
ὈΔΥΣΣΕΎΣ
```
👉 after
```nushell
~ l> "ὈΔΥΣΣΕΎΣ" | str downcase
ὀδυσσεύς
```

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`

adds two tests
- `non_ascii_upcase`
- `non_ascii_downcase`
