Refactor explore cursor code (#12979)
`explore` has 3 cursor-related structs that are extensively used to
track the currently shown "window" of the data being shown. I was
finding the cursor code quite difficult to follow, so this PR:
- rewrites the base `Cursor` struct from scratch, with some tests
- makes big changes to `WindowCursor`
- renames `XYCursor` to `WindowCursor2D`
- makes some of the cursor functions fallible as a start towards better
error handling
- changes lots of function names to things that I find more intuitive
- adds comments, including ASCII diagrams to explain how the cursors
work

More work could be done (I'd like to review/change more function names
in `WindowCursor` and `WindowCursor2D` and add more tests), but this is
the limit of what I can get done in a weekend. I think this part of the
code is in a better place now.

# Testing performed

I did a lot of manual testing in the record view and binary viewer,
moving around with arrow keys / page up+down / home+end.

This can definitely wait until after the release freeze, this area has
very few automated tests and it'd be good to let the changes bake a bit.

Span ID Refactor - Step 1 (#12960)
# Description
First part of SpanID refactoring series. This PR adds a `SpanId` type
and a corresponding `span_id` field to `Expression`. Parser creating
expressions will now add them to an array in `StateWorkingSet`,
generates a corresponding ID and saves the ID to the Expression. The IDs
are not used anywhere yet.

For the rough overall plan, see
https://github.com/nushell/nushell/issues/12963.

# User-Facing Changes
Hopefully none. This is only a refactor of Nushell's internals that
shouldn't have visible side effects.

msgpackz: increase default compression level (#13035)
# Description
Increase default compression level for brotli on msgpackz to 3. This has
the best compression time generally. Level 0 and 1 give weird results
and sometimes cause extremely inflated outputs rather than being
compressed. So far this hasn't really been a problem for the plugin
registry file, but has been for other data.

The `$example` is the web-app example from https://json.org/example.html

Benchmarked with:

```nushell
seq 0 11 | each { |level|
  let compressed = ($example | to msgpackz --quality $level)
  let time = (timeit { $example | to msgpackz --quality $level })
  {
    level: $level
    time: $time
    length: ($compressed | bytes length)
    ratio: (($uncompressed_length | into float) / ($compressed | bytes length))
  }
}
```

```

complete the type of --error-label in std assert commands (#12998)
i was looking at the website documentation of `std assert` and i noticed
one thing
- the `--error-label` argument of `assert` and `assert not` was just a
`record` -> now it's that complete type `record<text: string, span:
record<start: int, end: int>>`

Try to preserve the ordering of elements in from toml (#13045)
# Description

Enable the `preserve_order` feature of the `toml` crate to preserve the
ordering of elements when converting from/to toml.

Additionally, use `to_string_pretty()` instead of `to_string()` in `to
toml`. This displays arrays on multiple lines instead of one big single
line. I'm not sure if this one is a good idea or not... Happy to remove
this from this PR if it's not.

# User-Facing Changes
The order of elements will be different when using `from toml`. The
formatting of arrays will also be different when using `to toml`. For
example:

- before
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ bar │ 2 │
│ doo │ 3 │
│ foo │ 1 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = ["a", "b", "c", "d"]
```
- after
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ foo │ 1 │
│ bar │ 2 │
│ doo │ 3 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = [
    "a",
    "b",
    "c",
    "d",
]
```

Make LS_COLORS functionality faster in explore, especially on Windows (#12984)
Closes #12980. More context there, but basically `explore` was getting
file metadata for every row every time the record view was rendered. The
quick fix for now is to do the `LS_COLORS` colouring with a `&str`
instead of a path and file metadata.

Fix run_external::expand_glob() to return paths that are PWD-relative but reflect the original intent (#13028)
# Description

Fix #13021

This changes the `expand_glob()` function to use
`nu_engine::glob_from()` so that absolute paths are actually preserved,
rather than being made relative to the provided parent. This preserves
the intent of whoever wrote the original path/glob, and also makes it so
that tilde always produces absolute paths.

I also made `expand_glob()` handle Ctrl-C so that it can be interrupted.

Disallow more characters in arguments for internal cmd commands (#13009)
# Description
Makes `run-external` error if arguments to `cmd.exe` internal commands
contain newlines or a percent sign. This is because the percent sign can
expand environment variables, potentially? allowing command injection.
Newlines I think will truncate the rest of the arguments and should
probably be disallowed to be safe.

# After Submitting
- If the user calls `cmd.exe` directly, then this bypasses our
handling/checking for internal `cmd` commands. Instead, we use the
handling from the Rust std lib which, in this case, does not do special
handling and is potentially unsafe. Then again, it could be the user's
specific intention to run `cmd` with whatever trusted input. The problem
is that since we use the std lib handling, it assumes the exe uses the C
runtime escaping rules and will perform some unwanted escaping. E.g., it
will add backslashes to the quotes in `cmd echo /c '""'`.
- If `cmd` is called indirectly via a `.bat` or `.cmd` file, then we use
the Rust std lib which has separate handling for bat files that should
be safe, but will reject some inputs.
- ~~I'm not sure how we handle `PATHEXT`, that can also cause a file
without an extension to be run as a bat file. If so, I don't know where
the handling, if any, is done for that.~~ It looks like we use the
`which` crate to do the lookup using `PATHEXT`. Then, we pass the exe
path from that to the Rust std lib `Command`, which should be safe
(except for the first `cmd.exe` note).

So, in the future we need to unify and/or fix these different
implementations, including our own special handling for internal `cmd`
commands that this PR tries to fix.

Restore tilde expansion on external command names (#13001)
# Description

Fix a regression introduced by #12921, where tilde expansion was no
longer done on the external command name, breaking things like

```nushell
> ~/.cargo/bin/exa
```

This properly handles quoted strings, so they don't expand:

```nushell
> ^"~/.cargo/bin/exa"
Error: nu:🐚:external_command

  × External command failed
   ╭─[entry #1:1:2]
 1 │ ^"~/.cargo/bin/exa"
   ·  ─────────┬────────
   ·           ╰── Command `~/.cargo/bin/exa` not found
   ╰────
  help: `~/.cargo/bin/exa` is neither a Nushell built-in or a known external command

```

This required a change to the parser, so the command name is also parsed
in the same way the arguments are - i.e. the quotes on the outside
remain in the expression. Hopefully that doesn't break anything else. 🤞

Fixes #13000. Should include in patch release 0.94.1

cc @YizhePKU

# User-Facing Changes
- Tilde expansion now works again for external commands
- The `command` of `run-external` will now have its quotes removed like
the other arguments if it is a literal string
- The parser is changed to include quotes in the command expression of
`ExternalCall` if they were present

# Tests + Formatting
I would like to add a regression test for this, but it's complicated
because we need a well-known binary within the home directory, which
just isn't a thing. We could drop one there, but that's kind of a bad
behavior for a test to do. I also considered changing the home directory
for the test, but that's so platform-specific - potentially could get it
working on specific platforms though. Changing `HOME` env on Linux
definitely works as far as tilde expansion works.

make polars plugin use mimalloc (#12967)
# Description
@maxim-uvarov did a ton of research and work with the dply-rs author and
ritchie from polars and found out that the allocator matters on macos
and it seems to be what was messing up the performance of polars plugin.
ritchie suggested to use jemalloc but i switched it to mimalloc to match
nushell and it seems to run better.

## Before (default allocator)

Do not propagate glob creation error for external args (#12955)
# Description
Instead of returning an error, this PR changes `expand_glob` in
`run_external.rs` to return the original string arg if glob creation
failed. This makes it so that, e.g.,
```nushell
^echo `[`
^echo `***`
```
no longer fail with a shell error. (This follows from #12921.)

Allow byte streams with unknown type to be compatiable with binary (#12959)
# Description
Currently, this pipeline doesn't work `open --raw file | take 100`,
since the type of the byte stream is `Unknown`, but `take` expects
`Binary` streams. This PR changes commands that expect
`ByteStreamType::Binary` to also work with `ByteStreamType::Unknown`.
This was done by adding two new methods to `ByteStreamType`:
`is_binary_coercible` and `is_string_coercible`. These return true if
the type is `Unknown` or matches the type in the method name.

Make from json --objects streaming (#12949)
# Description

Makes the `from json --objects` command produce a stream, and read
lazily from an input stream to produce its output.

Also added a helper, `PipelineData::get_type()`, to make it easier to
construct a wrong type error message when matching on `PipelineData`. I
expect checking `PipelineData` for either a string value or an `Unknown`
or `String` typed `ByteStream` will be very, very common. I would have
liked to have a helper that just returns a readable stream from either,
but that would either be a bespoke enum or a `Box<dyn BufRead>`, which
feels like it wouldn't be so great for performance. So instead, taking
the approach I did here is probably better - having a function that
accepts the `impl BufRead` and matching to use it.

# User-Facing Changes

- `from json --objects` no longer collects its input, and can be used
for large datasets or streams that produce values over time.

# Tests + Formatting
All passing.

explore cleanup: remove+move binary viewer config (#12920)
Small change, removing 4 more configuration options from `explore`'s
binary viewer:

1. `show_index`
2. `show_data`
3. `show_ascii`
4. `show_split`

These controlled whether the 3 columns in the binary viewer (index, hex
data, ASCII) and the pipe separator (`|`) in between them are shown. I
don't think we need this level of configurability until the `explore`
command is more mature, and maybe even not then; we can just show them
all.

I think it's very unlikely that anyone is using these configuration
points.

Also, the row offset (e.g. how many rows we have scrolled down) was
being stored in config/settings when it's arguably not config; more like
internal state of the binary viewer. I moved it to a more appropriate
location and renamed it.

Rewrite run_external.rs (#12921)
This PR is a complete rewrite of `run_external.rs`. The main goal of the
rewrite is improving readability, but it also fixes some bugs related to
argument handling and the PATH variable (fixes
https://github.com/nushell/nushell/issues/6011).

I'll discuss some technical details to make reviewing easier.

## Argument handling

Quoting arguments for external commands is hard. Like, *really* hard.
We've had more than a dozen issues and PRs dedicated to quoting
arguments (see Appendix) but the current implementation is still buggy.

Here's a demonstration of the buggy behavior:

```nu
let foo = "'bar'"
^touch $foo            # This creates a file named `bar`, but it should be `'bar'`
^touch ...[ "'bar'" ]  # Same
```

I'll describe how this PR deals with argument handling.

First, we'll introduce the concept of **bare strings**. Bare strings are
**string literals** that are either **unquoted** or **quoted by
backticks** [^1]. Strings within a list literal are NOT considered bare
strings, even if they are unquoted or quoted by backticks.

When a bare string is used as an argument to external process, we need
to perform tilde-expansion, glob-expansion, and inner-quotes-removal, in
that order. "Inner-quotes-removal" means transforming from
`--option="value"` into `--option=value`.

## `.bat` files and CMD built-ins

On Windows, `.bat` files and `.cmd` files are considered executable, but
they need `CMD.exe` as the interpreter. The Rust standard library
supports running `.bat` files directly and will spawn `CMD.exe` under
the hood (see
[documentation](https://doc.rust-lang.org/std/process/index.html#windows-argument-splitting)).
However, other extensions are not supported [^2].

Nushell also supports a selected number of CMD built-ins. The problem
with CMD is that it uses a different set of quoting rules. Correctly
quoting for CMD requires using
[Command::raw_arg()](https://doc.rust-lang.org/std/os/windows/process/trait.CommandExt.html#tymethod.raw_arg)
and manually quoting CMD special characters, on top of quoting from the
Nushell side. ~~I decided that this is too complex and chose to reject
special characters in CMD built-ins instead [^3]. Hopefully this will
not affact real-world use cases.~~ I've implemented escaping that works
reasonably well.

## `which-support` feature

The `which` crate is now a hard dependency of `nu-command`, making the
`which-support` feature essentially useless. The `which` crate is
already a hard dependency of `nu-cli`, and we should consider removing
the `which-support` feature entirely.

## Appendix

Here's a list of quoting-related issues and PRs in rough chronological
order.

* https://github.com/nushell/nushell/issues/4609
* https://github.com/nushell/nushell/issues/4631

[^1]: The idea that backtick-quoted strings act like bare strings was
introduced by Kubouch and briefly mentioned in [the language
reference](https://www.nushell.sh/lang-guide/chapters/strings_and_text.html#backtick-quotes).

[^2]: The documentation also said "running .bat scripts in this way may
be removed in the future and so should not be relied upon", which is
another reason to move away from this. But again, quoting for CMD is
hard.

[^3]: If anyone wants to try, the best resource I found on the topic is
[this](https://daviddeley.com/autohotkey/parameters/parameters.htm).

Implement streaming I/O for CSV and TSV commands (#12918)
# Description

Implements streaming for:

- `from csv`
- `from tsv`
- `to csv`
- `to tsv`

via the new string-typed ByteStream support.

# User-Facing Changes
Commands above. Also:

- `to csv` and `to tsv` now have `--columns <List(String)>`, to provide
the exact columns desired in the output. This is required for them to
have streaming output, because otherwise collecting the entire list is
necessary to determine the output columns. If we introduce
`TableStream`, this may become less necessary.

Add support for the ps command on FreeBSD, NetBSD, and OpenBSD (#12892)
# Description

I feel like it's a little sad that BSDs get to enjoy almost everything
other than the `ps` command, and there are some tests that rely on this
command, so I figured it would be fun to patch that and make it work.

The different BSDs have diverged from each other somewhat, but generally
have a similar enough API for reading process information via
`sysctl()`, with some slightly different args.

This supports FreeBSD with the `freebsd` module, and NetBSD and OpenBSD
with the `netbsd` module. OpenBSD is a fork of NetBSD and the interface
has some minor differences but many things are the same.

I had wanted to try to support DragonFlyBSD too, but their Rust version
in the latest release is only 1.72.0, which is too old for me to want to
try to compile rustc up to 1.77.2... but I will revisit this whenever
they do update it. Dragonfly is a fork of FreeBSD, so it's likely to be
more or less the same - I just don't want to enable it without testing
it.

Fixes #6862 (partially, we probably won't be adding `zfs list`)

# User-Facing Changes
`ps` added for FreeBSD, NetBSD, and OpenBSD.

# Tests + Formatting
The CI doesn't run tests for BSDs, so I'm not entirely sure if
everything was already passing before. (Frankly, it's unlikely.) But
nothing appears to be broken.

# After Submitting
- [ ] release notes?
- [ ] DragonflyBSD, whenever they do update Rust to something close
enough for me to try it

Add completer for std help (#12929)
# Description

While each of the `help <subcommands>` in `std` had completers, there
wasn't one for the main `help` command.

This adds all internals and custom commands (as with `help commands`) as
possible completions.

# User-Facing Changes

`help ` + <kbd>Tab</kbd> will now suggest completions for both the `help
<subcommands>` as well as all internal and custom commands.

# Tests + Formatting

Note: Cannot add tests for completion functions since they are
module-internal and not visible to test cases, that I can see.

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