Fix a bug where the branch picker would be dismissed before completing
the add remote flow, thus making Zed unable to add remote repositories
through the branch picker.

This bug was caused by the picker always being dismissed on the confirm
action, so the fix was stopping the branch modal from being dismissed
too early.

I also cleaned up the UI a bit and code.

1. Removed the loading field from the Branch delegate because it was
never used and the activity indicator will show remote add command if it
takes a while.
2. I replaced some async task spawning with the use of `cx.defer`.
3. Added a `add remote name` fake entry when the picker is in the name
remote state. I did this so the UI would be consistent with the other
states.
4. Added two regression tests. 
4.1 One to prevent this bug from occurring again:
https://github.com/zed-industries/zed/pull/44742
4.2 Another to prevent the early dismissal bug from occurring 
5. Made `init_branch_list_test` param order consistent with Zed's code
base

This fixes an issue where a user could get confused by the branch picker
because it would only show the 10 most recent branches, instead of all
branches.

Currently we have a single cache for this data shared between all
snapshots which is incorrect, as we might update the cache to a new
version while having old snapshots around which then may try to access
new data with old offsets/rows.

The problem with inserting the absolute paths is that the agent will try
to read them. However, we don't allow the agent to read files outside
the current project. For now, we will only insert the crease in case the
code that is getting pasted is from the same project

Release Notes:

- Fixed an issue where pasting code into the agent panel from another
window would show an error

cc @11happy, we need to do a bit more than just running `git hook
pre-push` before pushing, as described

[here](https://github.com/zed-industries/zed/pull/42946#issuecomment-3550570438).
Right now this is also running the pre-push hook twice.

Fixes a few cases where the commit view would layout shift as the diff
loaded. This was caused by:
- Adding the commit message buffer after all the diff files
- Using the gutter dimensions from the last frame for the avatar spacing

Only by reusing the previous scroll handle, we can ensure that both the
scrollbar remains usable and also that the scrollbar does not flicker.
Previously, the scrollbar would hold the reference to an outdated
handle.

I tried invalidating the handle the scrollbar uses, but that leads to
flickering, which is worse. Hence, let's just reuse the scrollbar here.

Release Notes:

- Fixed an issue where the scrollbar would become stale in the code
completions menu after the items were updated.

For qualified identifiers we end up requesting both the definition of
the module and the item within it, but we only want the latter. At the
moment, we can't skip the request altogether, because we can't tell them
apart from the highlights query. However, we can tell from the target
range length, because it should be small for individual definitions as
it only covers their name, not the whole body.

Release Notes:

- N/A

We reallocate quite a bunch in this codepath even though we don't need
to, we already roughly know what number of elements we are working with
so we can reduce the required allocations to some degree. This also
reduces the amount of anchor comparisons required.

Fixes a bug that led to us unnecessarily restarting a language server
when we were looking at a single file of a given language.

Release Notes:

- Fixed a bug that led to Zed sometimes starting an excessive amount of

## Closes #43887

## Release Notes:

### Problem
DeepSeek's reasoning mode API requires `reasoning_content` to be
included in assistant messages that precede tool calls. Without it, the
API returns a 400 error:

```
Missing `reasoning_content` field in the assistant message at message index 2
```

### Added/Fixed/Improved
- Add `reasoning_content` field to `RequestMessage::Assistant` in
`crates/deepseek/src/deepseek.rs`
- Accumulate thinking content from `MessageContent::Thinking` and attach
it to the next assistant/tool-call message
- Wire reasoning content through the language model provider in
`crates/language_models/src/provider/deepseek.rs`

### Testing
- Verified with DeepSeek Reasoner model using tool calls
- Confirmed reasoning content is properly included in API requests

Fixes tool-call errors when using DeepSeek's reasoning mode.

While this fixes the link in the Readme it breaks the one in the docs
which is the more important one (we should probably just duplicate the
readme and not include it into gpui.rs but that is annoying).

Internally we noticed some regression related to removed query for
PascalCase identifiers. Reverting now to prevent this from going to
preview, still planning to land this with the necessary fixes later.

Introduces RotateSelectionsForward and RotateSelectionsBackward actions
that rotate content in a circular fashion across multiple cursors.

Behavior based on context:
- With selections: rotates the selected text at each cursor position
(e.g., x=1, y=2, z=3 becomes x=3, y=1, z=2)
- With just cursors: rotates entire lines at cursor positions (e.g.,
three lines cycle to line3, line1, line2)

Selections are preserved after rotation, allowing repeated cycling.
Useful for quickly rearranging values, lines, or arguments.

For more examples and use cases, please refer to #5315.

I'm eager to read your thoughts and make any adjustments or improvements
to any aspect of this change.

Closes #5315

Release Notes:

- Added `RotateSelectionsForward` and `RotateSelectionsBackward` actions
that rotate content in a circular fashion across multiple cursors

Hopefully addresses #43575. cc @cole-miller

**Summary**
When users selected text and pressed opening brackets (`(`, `[`, `{`),
the text was deleted instead of being wrapped.

- Added bracket pairs: `()`, `[]`, `{}`, `""`, `''` with `surround =
true`
- Added `surround = true` to existing bracket pairs
- Added `()` bracket pair

**Production Build Fix** (`crates/languages/src/lib.rs`)
- Fixed bug where `brackets` config was stripped in non-`load-grammars`
builds
- Preserved `brackets: config.brackets` in production mode

Closes #41186
