This PR makes it so we include some textual content in the user messages
that as used to send up tool results.

I observed that when sending up the tool results with no text, it would
lead the model to start replying with no text, which would then result
in an error when attaching later tool results.

I think there's a deeper issue at play here, but for now we just include
some text to keep the model on track.

This PR adds an optimistic update when staging or unstaging diff hunks.
In the process, I've also refactored the logic for staging and unstaging
hunks, to consolidate more of it in the `buffer_diff` crate.

I've also changed the way that we treat untracked files. Previously, we
maintained an empty diff for them, so as not to show unwanted
entire-file diff hunks in a regular editor. But then in the project diff
view, we had to account for this, and replace these empty diffs with
entire-file diffs. This form of state management made it more difficult
to store the pending hunks, so now we always use the same
`BufferDiff`/`BufferDiffSnapshot` for untracked files (with a single
hunk spanning the entire buffer), but we just have a special case in
regular buffers, that avoids showing that entire-file hunk.

* [x] Avoid creating a long queue of `set_index` operations when
staging/unstaging rapidly
* [x] Keep pending hunks when diff is recalculated without base text
changes
* [x] Be optimistic even when staging the single hunk in added/deleted
files
* Testing

This PR updates the ui of the git panel. It removes the header from the
panel and unifies the repository, branch and commit controls in the
bottom section.

It also adds a secondary menu to the primary button giving access to a
variety of actions for managing local and remote changes:

Closes #10004

This PR adds support for the organize imports action. Previously, you
had to manually configure it in the settings and then use format to run
it.

Note: Default key binding will be `alt-shift-o` which is similar to
VSCode's organize import. Also, because `cmd-shift-o` is taken by
outline picker.

Todo:

- [x] Initial working
- [x] Handle remote
- [x] Handle multi buffer
- [x] Can we make it generic for executing any code action?

Release Notes:

- Added `editor:OrganizeImports` action to organize imports (sort,
remove unused, etc) for supported LSPs. You can trigger it by using the
`alt-shift-o` key binding.

I've been bothered by using simple hyphens for bullet lists here for a
while; it kinda looked cheap and not well-formatted. So, in this PR, I'm
adding a new, custom UI component in the `language_models` crate, called
`InstructionListItem`, based off the `ListItem` that's somewhat
mimic'ing what a `<li>` would be on the web.

It does have a "rigid" structure as in it's always a label followed by a
button (which is optional), but that seems okay given it has been the
overall shape of the copy we've been using here. Also, never really
loved that we were pasting URLs directly, that kinda felt cheap, too. I
could see an argument where it's just clearer, but it looks too
cluttered, as URLs aren't super pretty, necessarily.

We currently only check the log size limit at startup and move `Zed.log`
to `Zed.log.old`. If a user runs Zed for an extended period, there's no
runtime restriction on the log file size, which can cause it to grow to
several gigabytes.

This PR fixes that by tracking the log file size while writing. If it
exceeds a certain threshold, we perform the same log replace and
continue logging.

Release Notes:

- Fixed an issue where `Zed.log` could grow excessively large during
long sessions of Zed.

Release Notes:

- Fixes Rust test tasks showing up outside of tests

This PR replaces almost all uses of "discard" in the git panel UI with
"restore", since that's the verb we settled on for the project diff.

The only exception is in the confirmation prompt for restoring files,
where I've kept the "discard changes" language. I think consistency is
less important here and it's helpful to rephrase the action that's being
taken to emphasize that it's destructive.

Closes #25471

In languages like Swift, names can be concatinated in form like `class
Example: UI`, notice here `Example` and `:` are two different words.
Before, `name_ranges`translation of above text would look like:

```
"class" -> [0..5]
" Example" -> [5..13] (Spaces are intentional)
"e:" -> [12..14] (This is incorrect, and should be ":" -> [13..14])
" UI" -> [14..16]
```

Because this translation does not account for concatinated words, this
might affect queries, but most importantly this panics when multi-byte
character (`ф`) is used in place of `e`, as it then tries to access
index which lies inside that multi-byte. For example, it panics on
`class Examplф: UI`.

---

This PR fixes this by handing concatinated words when calculating
`name_ranges`.

Now, the corrected ranges will look like:

```
"class" -> [0..5]
" Example" -> [5..13]
":" -> [13..14] (Now it's correct)
" UI" -> [14..16]
```

and for multi-byte character

```
"class" -> [0..5]
" Examplф" -> [5..14] (Notice ф takes two bytes)
":" -> [14..15]
" UI" -> [15..17]
```

This way, it no longer tries to access a previous index, preventing a
panic when that index contains a multi-byte character.

Release Notes:

- Fixed a panic when Cyrillic characters are used in languages like
Swift.
