Release Notes:

- git: Add keyboard shortcuts (when the panel is open) for fetch `ctrl-g
ctrl-g`, pull `ctrl-g down`, push `ctrl-g up`, force-push `ctrl-g
shift-up`, open diff `ctrl-g d`

Cherry-picked Restore git panel header (#26354)

Let's play around with it. This should not be added to tomorrow's

Release Notes:

- Git Beta: Added a panel header with an open diff and stage/unstage all
buttons.

Cherry-picked git_ui: Branch picker improvements (#26287)

- Truncate branch names based on the width of the picker
- Use a footer for "Create branch" instead of a picker entry

Still to do:

- [x] Select the footer button when no matches and run the create logic
on `enter`
- [x] Make it possible to quickly select the footer button from the
keyboard when there are matches

Release Notes:

- Git Beta: Removed limitation that made it impossible to create a
branch from the branch picker when it too closely resembled an existing
branch name

## Issue:

- `Generate Commit Message` will generate a random message if there are
no changes.

reparses.

You may need to zoom in hard to see this 😅 but the main addition of this
PR is just ensuring there's also horizontal border instead of just on
the bottom. Also added some box-shadow here to make it pop out of the
diff a bit more.

This is motivated by trying to make the Project Diff view usable with
huge Git change sets.

Release Notes:

- Improved performance of rendering multibuffers with very large numbers
of buffers

Release Notes:

- Git Beta: added `git:Add` as an alias for the existing `git::Diff`
- Git Beta: Fixed a bug where the 'generate commit message' keybinding
wasn't working.
- Git Beta: Made the empty project diff state a little more helpful with
a button to push, and a button to close the item.

This gives us _very_ rudimentary support for `git switch` and `git
checkout` now, by making them aliases for our existing `git::branch`
call.

Release Notes:

- Git Beta: Added `git::Switch` and `git::CheckoutBranch` as aliases for
the existing `git::Branch`

Release Notes:

- Git Beta: Fixed a few bugs where the suggested commit text wouldn't
show in certain cases, or would update slowly.

Release Notes:

- Resolved an issue where error messages from Git were not being
displayed in toast notifications.

This adds a setting for the "border" hunk display mode, as discussed,
and makes it the default.

Here's how it looks in light mode:

changes

This reduces the number of multibuffer syncs from 100,000 to 20,000.
Before this change each editor individually observed the project, so
literally any project change was amplified by the number of editors you
had open.

Now editors listen to their buffers instead of the project, and other
users of `cx.observe` on the project have been updated to use specific
events to reduce churn.

Follow up to #26237

Release Notes:

- Improved performance of Zed in large repos with lots of file system
events.

(cherry picked from commit 80fb88520f0c52b806ac963dca6a39bead1f49aa)

This reduces the number of multibuffer syncs when starting the editor
with 80
files open in the Zed repo from 10,000,000 to 100,000 by avoiding
O(n**2)
dirtyness checks.

Due to the snippet above, Zed is supposed to have `row` larger or equal
to `start_row` here:


https://github.com/zed-industries/zed/blob/205f9a9f0391da47a87cac45a41f67d2a23f5a95/crates/editor/src/element.rs#L1694

yet the panic were reported when clicking in the project diff.

That project diff has a lot of highlighting happening already, so the PR
disables inline diagnostics within a git diff view.

Removing the width here causes zed to use the default value (inside
default settings) after restart like other panels.

This PR adds a few more hunk style settings that flips the emphasis.
Normally, the concept at Zed has been that the project diff should
emphasize what's going into the commit. However, this leads to a problem
where the default state of all diff hunks are in the non-emphasized
state, making them hard to see and interact with. Especially on light
themes. This PR is an experiment in flipping the emphasis states. Now
the project diff is more like a queue of work, with the next "job" (hunk
to be evaluated) emphasized, and the "completed" (staged) hunks
deemphasized. This fixes the default state issue but is a big jump from
how we've been thinking about it. So here we can try it out and see how
it feels :)

Release Notes:

- Git Beta: Added hunk style settings to emphasize the unstaged state,
rather than the staged state.

- Git Beta: disable hunk restore action and button for created files

https://github.com/user-attachments/assets/b16e32e6-46c6-41dc-ab68-1824d288c8c2

This PR adds the first part of our planned extended notification system:
StatusToasts.

It also makes various updates to ComponentPreview and adds a `Styled`
extension in `ui::style::animation` to make it easier to animate styled
elements.

_**Note**: We will be very, very selective with what elements are
allowed to be animated in Zed. Assume PRs adding animation to elements
will all need to be manually signed off on by a designer._

## Status Toast

![CleanShot 2025-03-06 at 14 15
52@2x](https://github.com/user-attachments/assets/b65d4661-f8d1-4e98-b9be-2c05cba1409f)

These are designed to be used for notifying about things that don't
require an action to be taken or don't need to be triaged. They are
designed to be ignorable, and dismiss themselves automatically after a
set time.

They can optionally include a single action. 

Example: When the user enables Vim Mode, that action might let them undo
enabling it.

![CleanShot 2025-03-06 at 14 18
34@2x](https://github.com/user-attachments/assets/eb6cb20e-c968-4f03-88a5-ecb6a8809150)

Status Toasts should _not_ be used when an action is required, or for
any binary choice.

If the user must provide some input, this isn't the right component!

### Out of scope

- Toasts should fade over a short time (like AnimationDuration::Fast or
Instant) when dismissed
- We should visually show when the toast will dismiss. We'll need to
pipe the `duration_remaining` from the toast layer -> ActiveToast to do
this.
- Dismiss any active toast if another notification kind is created, like
a Notification or Alert.

This PR finishes up the support for generating commit messages using an
LLM.

We're shelling out to `git diff` to get the diff text, as it seemed more
efficient than attempting to reconstruct the diff ourselves from our
internal Git state.

Split Windows GHA CI job into `windows_clippy` and `windows_tests`
(`cargo test` and `cargo build`). `windows_clippy` will continue to run
on every PR commit, but `windows_tests` will only be run on main. Tag a
PR `windows` if you would like to run windows tests.

Added a call to the Azure metadata service to detect the Azure hardware
used by the GitHub hosted Windows runners. This is temporary and I'll
remove once I've gathered some data (adds 5-15secs to Windows CI times)
