This PR makes sure `$nu.default-config-dir` and `$nu.plugin-path` are
canonicalized.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

`$nu.default-config-dir` (and `$nu.plugin-path`) will now give canonical
paths, with symlinks and whatnot resolved.

I've added a couple of tests to check that even if the config folder
and/or any of the config files within are symlinks, the `$nu.*`
variables are properly canonicalized. These tests unfortunately only run
on Linux and MacOS, because I couldn't figure out how to change the
config directory on Windows. Also, given that they involve creating
files, I'm not sure if they're excessive, so I could remove one or two
of them.

Replace panics with errors in thread spawning (#12040)
# Description
Replace panics with errors in thread spawning.

Also adds `IntoSpanned` trait for easily constructing `Spanned`, and an
implementation of `From<Spanned<std::io::Error>>` for `ShellError`,
which is used to provide context for the error wherever there was a span
conveniently available. In general this should make it more convenient
to do the right thing with `std::io::Error` and always add a span to it
when it's possible to do so.

# User-Facing Changes
Fewer panics!

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`

Glob: don't allow implicit casting between glob and string (#11992)
# Description
As title, currently on latest main, nushell confused user if it allows
implicit casting between glob and string:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g } 
glob-test $x
```
It always expand the glob although `$x` is defined as a string.
This pr implements a solution from @kubouch :
> We could make it really strict and disallow all autocasting between
globs and strings because that's what's causing the "magic" confusion.
Then, modify all builtins that accept globs to accept oneof(glob,
string) and the rules would be that globs always expand and strings
never expand

# User-Facing Changes
After this pr, user needs to use `into glob` to invoke `glob-test`, if
user pass a string variable:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g } 
glob-test ($x | into glob)
```
Or else nushell will return an error.
```
 3 │ glob-test $x
   ·           ─┬
   ·            ╰── can't convert string to glob

Currently, there's multiple places that look for a config directory, and
each of them has different error messages when it can't be found. This
PR makes a `ConfigDirNotFound` error to standardize the error message
for all of these cases.

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

Previously, the errors in `create_nu_constant()` would say which config
file Nushell was trying to get when it couldn't find the config
directory. Now it doesn't. However, I think that's fine, given that it
doesn't matter whether it couldn't find the config directory while
looking for `login.nu` or `env.nu`, it only matters that it couldn't
find it.

This is what the error looks like:

Span fields were previously renamed to `internal_span` to discourage
their use in Rust code, but this change also affected the serde I/O for
Value. I don't believe the Python plugin was ever updated to reflect
this change.

This effectively changes it back, but just for the serialized form.
There are good reasons for doing this:

1. `internal_span` is a much longer name, and would be one of the most
common strings found in serialized Value data, probably bulking up the
plugin I/O

2. This change was never really meant to have implications for plugins,
and was just meant to be a hint that `.span()` should be used instead in
Rust code.

When Span refactoring is complete, the serialized form of Value will
probably change again in some significant way, so I think for now it's
best that it's left like this.

This has implications for #11911, particularly for documentation and for
the Python plugin as that was already updated in that PR to reflect
`internal_span`. If this is merged first, I will update that PR.

This would probably be considered a breaking change as it would break
plugin I/O compatibility (but not Rust code). I think it can probably go
in any major release though - all things considered, it's pretty minor,
and users are already expected to recompile plugins for new major
versions. However, it may also be worth holding off to do it together
with #11911 as that PR makes breaking changes in general a little bit
friendlier.

- 🟢 `toolkit fmt`

Nothing outside of `Value` itself had to be changed to make tests pass.
I did not check the Python plugin and whether it works now, but it was
broken before. It may work again as I think the main incompatibility it
had was expecting to use `span`

Related to #11928 - `tee --stderr` doesn't really work as expected
without it

Print stderr streams to stderr in `pipeline_data::print_if_stream()`

This corrects unexpected behavior if a stream from an external program
is transformed while still preserving its stderr output. Before this
change, that output is just drained and discarded. Worse, it's drained
to a buffer, which could be really slow and memory hungry if there's a
lot of output on stderr.

This is needed to make `tee --stderr` function in a non-surprising way.
See #11928

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

A script that was erroneously not producing stderr output before might
now, but I can't think of a lot of examples of an external stream being
transformed without being converted.

open, rm, umv, cp, rm and du: Don't globs if inputs are variables or string interpolation (#11886)
# Description
This is a follow up to
https://github.com/nushell/nushell/pull/11621#issuecomment-1937484322

Also Fixes: #11838 

## About the code change
It applys the same logic when we pass variables to external commands:


0487e9ffcb/crates/nu-command/src/system/run_external.rs (L162-L170)

That is: if user input dynamic things(like variables, sub-expression, or
string interpolation), it returns a quoted `NuPath`, then user input
won't be globbed
 
# User-Facing Changes
Given two input files: `a*c.txt`, `abc.txt`

* `let f = "a*c.txt"; rm $f` will remove one file: `a*c.txt`. 
~* `let f = "a*c.txt"; rm --glob $f` will remove `a*c.txt` and
`abc.txt`~
* `let f: glob = "a*c.txt"; rm $f` will remove `a*c.txt` and `abc.txt`

## Rules about globbing with *variable*
Given two files: `a*c.txt`, `abc.txt`
| Cmd Type | example | Result |
| ----- | ------------------ | ------ |
| builtin | let f = "a*c.txt"; rm $f | remove `a*c.txt` |
| builtin | let f: glob = "a*c.txt"; rm $f | remove `a*c.txt` and
`abc.txt`
| builtin | let f = "a*c.txt"; rm ($f \| into glob) | remove `a*c.txt`
and `abc.txt`
| custom | def crm [f: glob] { rm $f }; let f = "a*c.txt"; crm $f |
remove `a*c.txt` and `abc.txt`
| custom | def crm [f: glob] { rm ($f \| into string) }; let f =
"a*c.txt"; crm $f | remove `a*c.txt`
| custom | def crm [f: string] { rm $f }; let f = "a*c.txt"; crm $f |
remove `a*c.txt`
| custom | def crm [f: string] { rm $f }; let f = "a*c.txt"; crm ($f \|
into glob) | remove `a*c.txt` and `abc.txt`

In general, if a variable is annotated with `glob` type, nushell will
expand glob pattern. Or else, we need to use `into | glob` to expand
glob pattern

# Tests + Formatting
Done

# After Submitting
I think `str glob-escape` command will be no-longer required. We can
remove it.

# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.
-->

Debug assertions don't run at release, which means that `cargo test
--release` fails because the tests for name checks don't run properly.
These checks are not really expensive, and there shouldn't be any
noticeable difference to startup time, so there isn't much reason not to
just leave them in.

It's valuable to be able to run `cargo test --release`, as that can
expose race conditions and dependencies on undefined behavior that
aren't exposed in debug builds.

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

This shouldn't affect anything. Any violations of this rule were being
caught with debug tests, which are run by the CI.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr

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

wrapping run_repl with catch_unwind and restarting the repl on panic (#11860)
Provides the ability to cleanly recover from panics, falling back to the
last known good state of EngineState and Stack. This pull request also
utilizes miette's panic handler for better formatting of panics.

Specify which file not found in error (#11868)
# Description
Currently, `ShellError::FileNotFound` shows the span where the error
occurred but doesn't say which file wasn't found. This PR makes it so
the help includes that (like the `DirectoryNotFound` error).

# User-Facing Changes
No breaking changes, it's just that when a file can't be found, the help
will say which file couldn't be found:

Remove unused Index(Mut) impls on AST types (#11903)
# Description
Both `Block` and `Pipeline` had `Index`/`IndexMut` implementations to
access their elements, that are currently unused.
Explicit helpers or iteration would generally be preferred anyways but
in the current state the inner containers are `pub` and are liberally
used. (Sometimes with potentially panicking indexing or also iteration)

As it is potentially unclear what the meaning of the element from a
block or pipeline queried by a usize is, let's remove it entirely until
we come up with a better API.

# User-Facing Changes
None

Plugin authors shouldn't dig into AST internals

# Description
Hi, 

Fixes #10838, where before the `date` would be formatted incorrectly,
and was not picking `LC_TIME` for time formatting, but it picked the
first locale returned by the `sys-locale` crate instead. Now it will
format time based on `LC_TIME`. For example,

```
// my locale `nl_NL.UTF-8`
❯ date now | format date '%x %X'
20-02-24 17:17:12

$env.LC_TIME = "en_US.UTF-8"

❯ date now | format date '%x %X'
02/20/2024 05:16:28 PM
```
Note that I also changed the `default_env.nu` as otherwise the Time will
show AM/PM twice. Also reason for the `chrono` update is because this
relies on a fix to upstream repo, which i initially submitted an
[issue](https://github.com/chronotope/chrono/issues/1349#event-11765363286)

Add Value::coerce_str (#11885)
# Description
Following #11851, this PR adds one final conversion function for
`Value`. `Value::coerce_str` takes a `&Value` and converts it to a
`Cow<str>`, creating an owned `String` for types that needed converting.
Otherwise, it returns a borrowed `str` for `String` and `Binary`
`Value`s which avoids a clone/allocation. Where possible, `coerce_str`
and `coerce_into_string` should be used instead of `coerce_string`,
since `coerce_string` always allocates a new `String`.

Prune unused ParseError variants (#11881)
# Description
Error variants never raised should be removed to avoid confusion and
make sure we choose the proper variants in the future

- Remove unused `ParseError::InvalidModuleFileName`
- Remove unused `ParseError::NotFound`
- Remove unused `ParseError::MissingImportPattern`
- Remove unused `ParseError::ReadingFile`


# User-Facing Changes
None for users.
Insignificant for plugin authors as they interact only with `ShellError`

Name the Value conversion functions more clearly (#11851)
# Description
This PR renames the conversion functions on `Value` to be more consistent.
It follows the Rust [API guidelines](https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv) for ad-hoc conversions.
The conversion functions on `Value` now come in a few forms:
- `coerce_{type}` takes a `&Value` and attempts to convert the value to
`type` (e.g., `i64` are converted to `f64`). This is the old behavior of
some of the `as_{type}` functions -- these functions have simply been
renamed to better reflect what they do.
- The new `as_{type}` functions take a `&Value` and returns an `Ok`
result only if the value is of `type` (no conversion is attempted). The
returned value will be borrowed if `type` is non-`Copy`, otherwise an
owned value is returned.
- `into_{type}` exists for non-`Copy` types, but otherwise does not
attempt conversion just like `as_type`. It takes an owned `Value` and
always returns an owned result.
- `coerce_into_{type}` has the same relationship with `coerce_{type}` as
`into_{type}` does with `as_{type}`.
- `to_{kind}_string`: conversion to different string formats (debug,
abbreviated, etc.). Only two of the old string conversion functions were
removed, the rest have been renamed only.
- `to_{type}`: other conversion functions. Currently, only `to_path`
exists. (And `to_string` through `Display`.)

This table summaries the above:
| Form | Cost | Input Ownership | Output Ownership | Converts `Value`
case/`type` |
| ---------------------------- | ----- | --------------- |
---------------- | -------- |
| `as_{type}` | Cheap | Borrowed | Borrowed/Owned | No |
| `into_{type}` | Cheap | Owned | Owned | No |
| `coerce_{type}` | Cheap | Borrowed | Borrowed/Owned | Yes |
| `coerce_into_{type}` | Cheap | Owned | Owned | Yes |
| `to_{kind}_string` | Expensive | Borrowed | Owned | Yes |
| `to_{type}` | Expensive | Borrowed | Owned | Yes |

# User-Facing Changes
Breaking API change for `Value` in `nu-protocol` which is exposed as
part of the plugin API.

Spreading lists automatically when calling externals was deprecated in
0.89 (#11289), and this PR is to remove it in 0.91.

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

The new error message looks like this:

```
>  ^echo [1 2]
Error: nu:🐚:cannot_pass_list_to_external

  × Lists are not automatically spread when calling external commands
   ╭─[entry #13:1:8]
 1 │  ^echo [1 2]
   ·        ──┬──
   ·          ╰── Spread operator (...) is necessary to spread lists
   ╰────
  help: Either convert the list to a string or use the spread operator, like so: ...[1 2]
```

The old error message didn't say exactly where to put the `...` and
seemed to confuse a lot of people, so hopefully this helps.

Support redirect stderr and stdout+stderr with a pipe (#11708)
# Description
Close: #9673
Close: #8277
Close: #10944

This pr introduces the following syntax:
1. `e>|`, pipe stderr to next command. Example: `$env.FOO=bar nu
--testbin echo_env_stderr FOO e>| str length`
2. `o+e>|` and `e+o>|`, pipe both stdout and stderr to next command,
example: `$env.FOO=bar nu --testbin echo_env_mixed out-err FOO FOO e+o>|
str length`

Note: it only works for external commands. ~There is no different for
internal commands, that is, the following three commands do the same
things:~ Edit: it raises errors if we want to pipes for internal
commands
``` 
❯ ls e>| str length
Error:   × `e>|` only works with external streams
   ╭─[entry #1:1:1]
 1 │ ls e>| str length
   ·    ─┬─
   ·     ╰── `e>|` only works on external streams
   ╰────

❯ ls e+o>| str length
Error:   × `o+e>|` only works with external streams
   ╭─[entry #2:1:1]
 1 │ ls e+o>| str length
   ·    ──┬──
   ·      ╰── `o+e>|` only works on external streams
   ╰────
```

This can help us to avoid some strange issues like the following:

`$env.FOO=bar (nu --testbin echo_env_stderr FOO) e>| str length`

Which is hard to understand and hard to explain to users.

Enforce call stack depth limit for all calls (#11729)
# Description
Previously, only direcly-recursive calls were checked for recursion
depth. But most recursive calls in nushell are mutually recursive since
expressions like `for`, `where`, `try` and `do` all execute a separte
block.

```nushell
def f [] {
    do { f }
}
```
Calling `f` would crash nushell with a stack overflow.

I think the only general way to prevent such a stack overflow is to
enforce a maximum call stack depth instead of only disallowing directly
recursive calls.

This commit also moves that logic into `eval_call()` instead of
`eval_block()` because the recursion limit is tracked in the `Stack`,
but not all blocks are evaluated in a new stack. Incrementing the
recursion depth of the caller's stack would permanently increment that
for all future calls.

Fixes #11667

# User-Facing Changes
Any function call can now fail with `recursion_limit_reached` instead of
just directly recursive calls. Mutually-recursive calls no longer crash
nushell.

Fixes https://github.com/nushell/nushell/issues/11716

The problem is in our [record creation
API](0d518bf813/crates/nu-protocol/src/value/record.rs (L33))
which panics if the numbers of columns and values are different. I added
a safe variant that returns a `Result` and used it in the `rotate`
command.

## TODO in another PR:

Go through all `from_raw_cols_vals_unchecked()` (this includes the
`record!` macro which uses the unchecked version) and make sure that
either
a) it is guaranteed the number of cols and vals is the same, or
b) convert the call to `from_raw_cols_vals()`

Reason: Nushell should never panic.

fix exit_code handling when running a scripts with ctrlc (#11466)
# Description
Fixes: #11394

When run `^sleep 3` we have an `exit_code ListStream`, and when we press
ctrl-c, this `ListStream` will return None. But it's not expected,
because `exit_code` sender in `run_external` always send an exit code
out.

This pr is trying to fix the issue by introducing a `first_guard` into
ListStream, it will always generate a value from underlying stream if
`first_guard` is true, so it's guarantee to have at least one value to
return.

And the pr also do a little refactor, which makes use of
`ListStream::from_stream` rather than construct it manually.

# User-Facing Changes
## Before
```
> nu -c "^sleep 3"  # press ctrl-c

Unify glob behavior on open, rm, cp-old, mv, umv, cp and du commands (#11621)
# Description
This pr is a follow up to
[#11569](https://github.com/nushell/nushell/pull/11569#issuecomment-1902279587)
> Revert the logic in https://github.com/nushell/nushell/pull/10694 and
apply the logic in this pr to mv, cp, rv will require a larger change, I
need to think how to achieve the bahavior

And sorry @bobhy for reverting some of your changes.

This pr is going to unify glob behavior on the given commands:
* open
* rm
* cp-old
* mv
* umv
* cp
* du

So they have the same behavior to `ls`, which is:
If given parameter is quoted by single quote(`'`) or double quote(`"`),
don't auto-expand the glob pattern. If not quoted, auto-expand the glob
pattern.

Fixes: #9558  Fixes: #10211 Fixes: #9310 Fixes: #10364 

# TODO
But there is one thing remains: if we give a variable to the command, it
will always auto-expand the glob pattern, e.g:
```nushell
let path = "a[123]b"
rm $path
```
I don't think it's expected. But I also think user might want to
auto-expand the glob pattern in variables.

So I'll introduce a new command called `glob escape`, then if user
doesn't want to auto-expand the glob pattern, he can just do this: `rm
($path | glob escape)`

-->

## NOTE
This pr changes the semantic of `GlobPattern`, before this pr, it will
`expand path` after evaluated, this makes `nu_engine::glob_from` have no
chance to glob things right if a path contains glob pattern.

e.g: [#9310
](https://github.com/nushell/nushell/issues/9310#issuecomment-1886824030)
#10211

I think changing the semantic is fine, because it makes glob works if
path contains something like '*'.

It maybe a breaking change if a custom command's argument are annotated
by `: glob`.

Add into cell-path for dynamic cell-path creation (#11322)
# Description

The `cell-path` is a type that can be created statically with
`$.nested.structure.5`, but can't be created from user input. This makes
it difficult to take advantage of commands that accept a cell-path to
operate on data structures.

This PR adds `into cell-path` for dynamic cell-path creation.

`into cell-path` accepts the following input shapes:
* Bare integer (equivalent to `$.1`)
* List of strings and integers
* List of records with entries `value` and `optional`
* String (parsed into a cell-path)

## Example usage

An example of where `into cell-path` can be used is in working with `git
config --list`. The git configuration has a tree structure that maps
well to nushell records. With dynamic cell paths it is easy to convert
`git config list` to a record:

```nushell
git config --list
| lines
| parse -r '^(?<key>[^=]+)=(?<value>.*)'
| reduce --fold {} {|entry, result|
  let path = $entry.key | into cell-path

  $result
  | upsert $path {||
    $entry.value
  }
}
| select remote
```

Output:

```

## Errors

`lex()` + `parse_cell_path()` are forgiving about what is allowed in a
cell-path so it will allow what appears to be nonsense to become a
cell-path:

```nushell
let table = [["!@$%^&*" value]; [key value]]

$table | get ("!@$%^&*.0" | into cell-path)
# => key
```

But it will reject bad cell-paths:

```
❯ "a b" | into cell-path
Error: nu:🐚:cant_convert

  × Can't convert to cell-path.
   ╭─[entry #14:1:1]

This PR will allow string interpolation at parse time.

Since the actual config hasn't been loaded at parse time, this uses the
`get_config()` method on `StateWorkingSet`. So file sizes and datetimes
(I think those are the only things whose string representations depend
on the config) may be formatted differently from how users have
configured things, which may come as a surprise to some. It does seem
unlikely that anyone would be formatting file sizes or date times at
parse time. Still, something to think about if/before this PR merged.

Also, I changed the `ModuleNotFound` error to include the name of the
module.

# 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 do stuff like:

```nu
const x = [1 2 3]
const y = $"foo($x)" // foo[1, 2, 3]
```

The main use case is `use`-ing and `source`-ing files at parse time:

```nu
const file = "foo.nu"
use $"($file)"
```

If the module isn't found, you'll see an error like this:
```
Error: nu::parser::module_not_found

  × Module not found.
   ╭─[entry #3:1:1]
 1 │  use $"($file)"
   ·      ─────┬────
   ·           ╰── module foo.nu not found
   ╰────
  help: module files and their paths must be available before your script is run as parsing occurs before anything is evaluated
```

Although there's user-facing changes, there's probably no need to change
the docs since people probably already expect string interpolation to
work at parse time.

Edit: @kubouch pointed out that we'd need to document the fact that
stuff like file sizes and datetimes won't get formatted according to
user's runtime configs, so I'll make a PR to nushell.github.io after
this one

This PR is for using version 5.1 of
[byte_unit](https://docs.rs/byte-unit/latest/byte_unit/index.html)
instead of 4.0. dependabot opened
https://github.com/nushell/nushell/pull/11499 to do this but it's a
major version increment so some minor changes were necessary.

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

If something is on the boundary of a unit (e.g. 1024 bytes = 1
kibibytes), that will now be formatted as `1.0 KiB` where it used to be
formatted as `1,024 B`.

do not attempt to glob expand if the file path is wrapped in quotes (#11569)
# Description
Fixes: #11455

### For arguments which is annotated with `:path/:directory/:glob`
To fix the issue, we need to have a way to know if a path is originally
quoted during runtime. So the information needed to be added at several
levels:
* parse time (from user input to expression)
We need to add quoted information into `Expr::Filepath`,
`Expr::Directory`, `Expr::GlobPattern`
* eval time
When convert from `Expr::Filepath`, `Expr::Directory`,
`Expr::GlobPattern` to `Value::String` during runtime, we won't auto
expanded the path if it's quoted

### For `ls`
It's really special, because it accepts a `String` as a pattern, and it
generates `glob` expression inside the command itself.

So the idea behind the change is introducing a special SyntaxShape to
ls: `SyntaxShape::LsGlobPattern`. So we can track if the pattern is
originally quoted easier, and we don't auto expand the path either.

Then when constructing a glob pattern inside ls, we check if input
pattern is quoted, if so: we escape the input pattern, so we can run `ls
a[123]b`, because it's already escaped.
Finally, to accomplish the checking process, we also need to introduce a
new value type called `Value::QuotedString` to differ from
`Value::String`, it's used to generate an enum called `NuPath`, which is
finally used in `ls` function. `ls` learned from `NuPath` to know if
user input is quoted.

# User-Facing Changes
Actually it contains several changes
### For arguments which is annotated with `:path/:directory/:glob`
#### Before
```nushell
> def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a
/home/windsoilder/a
> def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a
/home/windsoilder/a
> def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a
/home/windsoilder/a
```
#### After
```nushell
> def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a')
~/a
~/a
> def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a')
~/a
~/a
> def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a')
~/a
~/a
```
### For ls command
`touch '[uwu]'`
#### Before
```
❯ ls -D "[uwu]"
Error:   × No matches found for [uwu]
   ╭─[entry #6:1:1]
 1 │ ls -D "[uwu]"
   ·       ───┬───
   ·          ╰── Pattern, file or folder not found
   ╰────

```

#### After
```

Add CLI flag to disable history (#11550)
# Description
Adds a CLI flag for nushell that disables reading and writing to the
history file. This will be useful for future testing and possibly our
users as well. To borrow `fish` shell's terminology, this allows users
to start nushell in "private" mode.

Allow plugins to receive configuration from the nushell configuration (#10955)
# Description

When nushell calls a plugin it now sends a configuration `Value` from
the nushell config under `$env.config.plugins.PLUGIN_SHORT_NAME`. This
allows plugin authors to read configuration provided by plugin users.

The `PLUGIN_SHORT_NAME` must match the registered filename after
`nu_plugin_`. If you register `target/debug/nu_plugin_config` the
`PLUGIN_NAME` will be `config` and the nushell config will loook like:

        $env.config = {
          # ...
          plugins: {
            config: [
              some
              values
            ]
          }
        }

Configuration may also use a closure which allows passing values from
`$env` to a plugin:

        $env.config = {
          # ...
          plugins: {
            config: {||
              $env.some_value
            }
          }
        }

This is a breaking change for the plugin API as the `Plugin::run()`
function now accepts a new configuration argument which is an
`&Option<Value>`. If no configuration was supplied the value is `None`.

Plugins compiled after this change should work with older nushell, and
will behave as if the configuration was not set.

Initially discussed in #10867

# User-Facing Changes

* Plugins can read configuration data stored in `$env.config.plugins`
* The plugin `CallInfo` now includes a `config` entry, existing plugins
will require updates

adjust some commansd input_output type (#11436)
# Description
1. Make table to be a subtype of `list<any>`, so some input_output_types
of filter commands are unnecessary
2. Change some commands which accept an input type, but generates
different output types. In this case, delete duplicate entry, and change
relative output type to `<any>`

Yeah it makes some commands more permissive, but I think it's better to
run into strange issue that why my script runs to failed during parse
time.
