Cherry-picked Disable indent guides for single line editors (#12584)

This PR disables indent guides by default for single line editors. Right
now indent guides show up in the project search editor (which is only a
single line)

Release Notes:

- Fixed an issue where indent guides would show up in a single line
editor (e.g. project search, buffer search)

Cherry-picked indent guides: Respect language specific settings in
multibuffers (#12528)

Indent guides can be configured per language, meaning that in a multi
buffer we can get excerpts where indent guides should be
disabled/enabled/styled differently than other excerpts.

Imagine the following scenario, i have indent guides disabled in my
settings, but want to enable them for JS and Python. I also want to use
a different line width for python files. Something like this is now
supported:

src="https://github.com/zed-industries/zed/assets/53836821/0c91411c-145c-4210-a883-4c469d5cb828">

And the relevant settings for the example above:
```json
"indent_guides": {
  "enabled": false
},
"languages": {
  "JavaScript": {
    "indent_guides": {
      "enabled": true
    }
  },
  "Python": {
    "indent_guides": {
      "enabled": true,
      "line_width": 5
    }
  }
}
```



Release Notes:

- Respect language specific settings when showing indent guides in a
multibuffer
- Fixes an issue where indent guide specific settings were not
recognized when specified in local settings

Cherry-picked indent guides: Use primary buffer language to determine
tab size (#12506)

When indent guides were still WIP, I thought it might be a good idea to
detect the tab size for every line individually, so we can handle files
with mixed indentations. However, while optimizing the performance of
indent guides I found that getting the language at a given anchor was
pretty expensive, therefore I only resolved the language for the first
visible row. However, this could lead to some weird flickering, where
the indent guides would use different tab sizes depending on the first
visible row (see #12492). This can be fixed by just using the primary
buffer language size.

So as of right now indent guides cannot handle files with mixed
indentations. Im not sure if anyone actually does/expects this, but one
use case I could imagine is something like this:
User x has a svelte file, where the tab size is set to `4`. However the
svelte code uses typescript inside a script tag, which User x wants to
use a tab size of `2`. The approach used here would not work for this,
but then again I think our formatter does not even support something
like this. Im probably overcomplicating things, so let's stick with the
simple solution for now.

Release Notes:

- Fixed an issue where indent guides would use an incorrect tab size
([#12492](https://github.com/zed-industries/zed/issues/12492)).

#12005 introduced a side effect, that would cause the editor to react to
a scroll event when using the middle mouse button to close a tab

Before:

After:


https://github.com/zed-industries/zed/assets/53836821/6ada7985-97c9-4b52-848f-c7f9461c5216

Release Notes:

- Fixed an issue where the editor would scroll upwards if other tabs
were closed using the middle mouse button

Release Notes:

- Improved clarity for inline transformations by always including the
active assistant context.

You can see in the video that hunks were getting toggled even when
clicking on the scrollbar.

This happened because the hitbox was actually extended to the left of
the hunk indicator, I believe that was done so that "Removed" hunk
indicators rendered correctly (Red triangles)

Fixed:

not on them)

Partially fixes #5119 
TODO:
- [ ] Change cursor style to Copy when dragging an entry with opt
pressed.

Release Notes:

- Drag-and-dropping a project panel entry with opt modifier pressed now
copies the entry instead of moving it.

This pull request fixes two issues in `RateLimiter` that caused
excessive rate-limiting to take place:

- c19083a35c89a22395595f8934c117a14943ed24 fixes a mistake that caused
us to load buckets from the database incorrectly and set the
`refill_time_per_token` to equal the `refill_duration`. This was the
primary reason why rate limiting was acting oddly.
- 34b88d14f6d9fde4d967554fc2e81498c1be3e26 fixes another slight logic
error that caused tokens to be underprovisioned. This was minor compared
to the bug above.

Release Notes:

- N/A

Release Notes:

- Added re-run task button to terminal title.

Fixes #9819

Release Notes:

- Fix wrap guides overlapping with the inline assistant
([#9819](https://github.com/zed-industries/zed/issues/9819)).

We should reintroduce this as part of the prompt library.

Release Notes:

- Removed an over-eager system prompt from the assistant that was
causing misbehavior. Going forward, our intent is to always let you
observe and edit text before we send it.

This PR changes the default value of the `calls.share_on_join` setting
from `true` to `false`.

Nathan mentioned that project sharing should be opt-in so that projects
aren't shared unless you intend for them to be.

Release Notes:

- Changed the default `calls.share_on_join` value to `false`.

Release Notes:

- Added support for `background_color` in `syntax` map in `theme.json`.

This adds support for setting a `background_color` for styles inside the
`syntax` map for themes defined in `theme.json`. The field is optional
so there should be no backwards compatibility issues.

It is worth noting that the current behaviour for selecting text is that
the background colours will mix/blend (I'm not sure the correct term
here). Changing this behaviour, or making it configurable, looks to be a
far more complex issue and I'm not sure I know how to do it.

This PR updates the Elixir docs with a note on how to switch to using
other language server.

Picks up https://github.com/kvark/blade/pull/118
Fixes #10351

Seeing that Zed loaded with Blade repository is consuming 260Mb of RAM.
We can tune this to be lower, but ultimately it doesn't matter: this
memory isn't wasted, it's just pools for memory and descriptors, which
may be used by bigger and more complex views of Zed.

This should make it less attention-grabbing.

slash command:


https://github.com/zed-industries/zed/assets/482957/62f39eae-d7d5-46bf-a356-dd081ff88312

Moreover, this also adds a status to pending slash commands, so that we
can show when a query is running or whether it failed:
