Simplify default style and match Rust code to config (#9900)
# Description

This PR aligns the default config in the Rust code to the default config
in the nushell file.

To do so, it removes closures from the default file, opting instead to
pick a simple style as default. This allows easier maintenance of both
Rust and Nushell code without removing the ability to use closures for
styling in your configuration.

The default theme is now "dark mode" in both the Rust and nushell config
code.

remove let-env, focus on mutating $env (#9574)
# Description

For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.

So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.

Before:

```
let-env FOO = "BAR"
```

Now:

```
$env.FOO = "BAR"
```

It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

revert: move to ahash (#9464)
This PR reverts https://github.com/nushell/nushell/pull/9391

We try not to revert PRs like this, though after discussion with the
Nushell team, we decided to revert this one.

The main reason is that Nushell, as a codebase, isn't ready for these
kinds of optimisations. It's in the part of the development cycle where
our main focus should be on improving the algorithms inside of Nushell
itself. Once we have matured our algorithms, then we can look for
opportunities to switch out technologies we're using for alternate
forms.

Much of Nushell still has lots of opportunities for tuning the codebase,
paying down technical debt, and making the codebase generally cleaner
and more robust. This should be the focus. Performance improvements
should flow out of that work.

Said another, optimisation that isn't part of tuning the codebase is
premature at this stage. We need to focus on doing the hard work of
making the engine, parser, etc better.

use "search_result" style to colorize matching strings (fixes #9275) (#9326)
This change introduces new `search_result` style supported in the color
config. The change also removes obsolete check for `config.ls_colors`
for computing the style. `config.ls_colors` has been removed last year,
so this removes the reference to the obsolete flag, along with a cleanup
that removes all the code that used to rely on ls_colors for
highlighting search results.

Bump tabled dependency to 0.11 (#8922)
close? #8060

Quite a bit of refactoring took place.
I believe a few improvements to collapse/expand were made.

I've tried to track any performance regressions and seems like it is
fine.

I've noticed something different now with default configuration path or
something in this regard?
So I might missed something while testing because of this.

Requires some oversight.

Add IDE support (#8745)
# Description

This adds a set of new flags on the `nu` binary intended for use in
IDEs. Here is the set of supported functionality so far:

* goto-def - go to the definition of a variable or custom command
* type hints - see the inferred type of variables
* check - see the errors in the document (currently only one error is
supported)
* hover - get information about the variable or custom command
* complete - get a completion list at the current position

Clean up unnecessary macro use (#8607)
Some minor code cleanup.

We've accumulated a few macros over the years that arguably don't need
to be macros. This PR removes 4 macros by either:
1. Inlining the macro
2. Replacing the macro with a local function
3. Replacing the macro with a closure

Add pattern matching (#8590)
# Description

This adds `match` and basic pattern matching.

An example:

```
match $x {
  1..10 => { print "Value is between 1 and 10" }
  { foo: $bar } => { print $"Value has a 'foo' field with value ($bar)" }
  [$a, $b] => { print $"Value is a list with two items: ($a) and ($b)" }
  _ => { print "Value is none of the above" }
}
```

Like the recent changes to `if` to allow it to be used as an expression,
`match` can also be used as an expression. This allows you to assign the
result to a variable, eg) `let xyz = match ...`

I've also included a short-hand pattern for matching records, as I think
it might help when doing a lot of record patterns: `{$foo}` which is
equivalent to `{foo: $foo}`.

There are still missing components, so consider this the first step in
full pattern matching support. Currently missing:
* Patterns for strings
* Or-patterns (like the `|` in Rust)
* Patterns for tables (unclear how we want to match a table, so it'll
need some design)
* Patterns for binary values
* And much more

Patch explore 4 (#7517)
ref #7339 - This PR updates explore to take some of the colors from

note: Not sure why this regression appeared maybe it's a feature or it's
no longer supposed to be supported?

add xterm color names to ansi --list (#7513)
# Description

Follow up to #7141 to map @webbedspace's rgb colors to xterm 256 color
indexes. Also added the xterm 256 named colors to `ansi --list` in the
process.

The few dozen or so names that were duplicate in the xterm 256 names
from [here](https://www.ditig.com/256-colors-cheat-sheet) were renamed
by appending a,b,c,d. So, instead of two blue3's there will be blue3a
and blue3b.

color_config now accepts closures as color values (#7141)
# Description

Closes #6909. You can now add closures to your `color_config` themes.
Whenever a value would be printed with `table`, the closure is run with
the value piped-in. The closure must return either a {fg,bg,attr} record
or a color name (`'light_red'` etc.). This returned style is used to
colour the value.

This is entirely backwards-compatible with existing config.nu files.

Example code excerpt:
```
let my_theme = {
    header: green_bold
    bool: { if $in { 'light_cyan' } else { 'light_red' } }
    int: purple_bold
    filesize: { |e| if $e == 0b { 'gray' } else if $e < 1mb { 'purple_bold' } else { 'cyan_bold' } }
    duration: purple_bold
    date: { (date now) - $in | if $in > 1wk { 'cyan_bold' } else if $in > 1day { 'green_bold' } else { 'yellow_bold' } }
    range: yellow_bold
    string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }
    nothing: white
```
Example output with this in effect:

Slightly important notes:

* Some color_config names, namely "separator", "empty" and "hints", pipe
in `null` instead of a value.
* Currently, doing anything non-trivial inside a closure has an
understandably big perf hit. I currently do not actually recommend
something like `string: { if $in =~ '^#\w{6}$' { $in } else { 'white' }
}` for serious work, mainly because of the abundance of string-type data
in the world. Nevertheless, lesser-used types like "date" and "duration"
work well with this.
* I had to do some reorganisation in order to make it possible to call
`eval_block()` that late in table rendering. I invented a new struct
called "StyleComputer" which holds the engine_state and stack of the
initial `table` command (implicit or explicit).
* StyleComputer has a `compute()` method which takes a color_config name
and a nu value, and always returns the correct Style, so you don't have
to worry about A) the color_config value was set at all, B) whether it
was set to a closure or not, or C) which default style to use in those
cases.
* Currently, errors encountered during execution of the closures are
thrown in the garbage. Any other ideas are welcome. (Nonetheless, errors
result in a huge perf hit when they are encountered. I think what should
be done is to assume something terrible happened to the user's config
and invalidate the StyleComputer for that `table` run, thus causing
subsequent output to just be Style::default().)
* More thorough tests are forthcoming - ran into some difficulty using
`nu!` to take an alternative config, and for some reason `let-env config
=` statements don't seem to work inside `nu!` pipelines(???)
* The default config.nu has not been updated to make use of this yet. Do
tell if you think I should incorporate that into this.

[MVP][WIP] less like pager (#6984)
Run it as `explore`.

#### example

```nu
ls | explore
```

Configuration points in `config.nu` file.
```
  # A 'explore' utility config
   explore_config: {
     highlight: { bg: 'yellow', fg: 'black' }
     status_bar: { bg: '#C4C9C6', fg: '#1D1F21' }
     command_bar: { fg: '#C4C9C6' }
     split_line: '#404040'
     cursor: true
     # selected_column: 'blue'
     # selected_row: { fg: 'yellow', bg: '#C1C2A3' }
     # selected_cell: { fg: 'white', bg: '#777777' }
     # line_shift: false,
     # line_index: false,
     # line_head_top: false,
     # line_head_bottom: false,
   }
```

You can start without a pipeline and type `explore` and it'll give you a
few tips.

![image](https://user-images.githubusercontent.com/343840/205088971-a8c0262f-f222-4641-b13a-027fbd4f5e1a.png)

If you type `:help` you an see the help screen with some information on
what tui keybindings are available.

![image](https://user-images.githubusercontent.com/343840/205089461-c4c54217-7ec4-4fa0-96c0-643d68dc0062.png)

From the `:help` screen you can now hit `i` and that puts you in
`cursor` aka `inspection` mode and you can move the cursor left right up
down and it you put it on an area such as `[table 5 rows]` and hit the
enter key, you'll see something like this, which shows all the `:`
commands. If you hit `esc` it will take you to the previous screen.

![image](https://user-images.githubusercontent.com/343840/205090155-3558a14b-87b7-4072-8dfb-dc8cc2ef4943.png)

If you then type `:try` you'll get this type of window where you can
type in the top portion and see results in the bottom.

![image](https://user-images.githubusercontent.com/343840/205089185-3c065551-0792-43d6-a13c-a52762856209.png)

The `:nu` command is interesting because you can type pipelines like
`:nu ls | sort-by type size` or another pipeline of your choosing such
as `:nu sys` and that will show the table that looks like this, which
we're calling "table mode".

![image](https://user-images.githubusercontent.com/343840/205090809-e686ff0f-6d0b-4347-8ed0-8c59adfbd741.png)

If you hit the `t` key it will now transpose the view to look like this.

![image](https://user-images.githubusercontent.com/343840/205090948-a834d7f2-1713-4dfe-92fe-5432f287df3d.png)

In table mode or transposed table mode you can use the `i` key to
inspect any collapsed field like `{record 8 fields}`, `[table 16 rows]`,
`[list x]`, etc.

One of the original benefits was that when you're in a view that has a
lot of columns, `explore` gives you the ability to scroll left, right,
up, and down.

`explore` is also smart enough to know when you're in table mode versus
preview mode. If you do `open Cargo.toml | explore` you get this.

![image](https://user-images.githubusercontent.com/343840/205091822-cac79130-3a52-4ca8-9210-eba5be30ed58.png)

If you type `open --raw Cargo.toml | explore` you get this where you can
scroll left, right, up, down. This is called preview mode.

![image](https://user-images.githubusercontent.com/343840/205091990-69455191-ab78-4fea-a961-feafafc16d70.png)

When you're in table mode, you can also type `:preview`. So, with `open
--raw Cargo.toml | explore`, if you type `:preview`, it will look like
this.

![image](https://user-images.githubusercontent.com/343840/205092569-436aa55a-0474-48d5-ab71-baddb1f43027.png)
