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.

This PR adds the `git.hunk_style` setting, allowing setting an alternate
style for hunks – specifically the rendering of unstaged hunks.

It has 2 options:

- `transparent` (unstaged hunks are more transparent/less opaque than
staged hunks)
- `pattern (unstaged hunks are indicated by a visual pattern)

We'll possibly explore a VSCode-style "don't show staged hunks", but the
complexity it adds is a bit out of scope for now.

Transparent:

Cherry-picked Fix a panic on Linux theme appearance change (#26019)

Closes https://github.com/zed-industries/zed/issues/26009

`with_common` panicked at `borrow_mut` which is the way it's implemented
for X11, Wayland and Headless Linux counterparts.

By accessing the appearance global instead of a `RefCell` with it, the
panic goes away with one notable side-effect, on Linux only: the first
global's value on `Dark` appearance would be `Light`: it becomes normal
instantly, thanks to

This does not fix the bug where, when the commit editor modal is open,
changing the staged file does not update the suggested message in the
commit editor. Conrad mentioned he thought we shouldn't be allowed to
change those when the modal is open, so I'm not attempting to fix that.

Release Notes:

- Made suggested commits placeholders and allow them to be committed.

Cherry-picked Skip .git/lfs FS events (#25927)

Closes https://github.com/zed-industries/zed/issues/25865
Closes https://github.com/zed-industries/zed/pull/25915

In the issue, Zed had caused `.git/lfs/tmp/466102258`-like files to
appear in the directory, which lead to background FS event listener to
handle this as an update, incrementing snapshot's `scan_id`, which lead
to git status rescan, which caused another increment to `status_scan_id`
— incrementing either of the IDs causes the related repo data to be
considered "changed:



https://github.com/zed-industries/zed/blob/41b45eaba798a56e596857fa497c862050788bc7/crates/worktree/src/worktree.rs#L1590-L1605

hence propagating events to the other parts of the system (e.g. git
blame, which was also active in the issue's case)

```
[2025-03-01T20:01:08+01:00 DEBUG worktree] ignoring event ".git/lfs/tmp/466102258" within unloaded directory
[2025-03-01T20:01:08+01:00 DEBUG worktree] received fs events []
[2025-03-01T20:01:08+01:00 DEBUG worktree] reloading repositories: ["/Users/alex/dev/monorepo/.git"]
[2025-03-01T20:01:08+01:00 DEBUG editor::git::blame] Status of git repositories updated. Regenerating blame data...
[2025-03-01T20:01:08+01:00 DEBUG editor::git::blame] Status of git repositories updated. Regenerating blame data...
[2025-03-01T20:01:08+01:00 DEBUG editor::git::blame] Status of git repositories updated. Regenerating blame data...
```

Due to repo update events sent, another `.git/lfs/tmp/` entry is
created, things start over...

The PR fixes this by ignoring any `.git/lfs/` directory-related FS
events, as needed for the current git status update heuristics.

https://github.com/zed-industries/zed/pull/25915 tried to follow further
and `scan_id` and `status_scan_id` but we do not store all git state in
memory, e.g. head

Cherry-picked Disable Git panel button to open commit editor in certain
cases (#26000)

Also:

- Internally renames a bit of code to make it easy to identify between
when we are disabling the buttons that open and close the modal editor
(in Git Panel and Project Diff) vs when we are disabling the commit
buttons (in Git Panel and Git commit editor modal).
- Deletes some unused code.

Release Notes:

- Unified disabling / enabling the button to open the Git commit editor
modal in the Git panel with the Project Diff commit button.
- Unified disabling / enabling the commit buttons, for the same cases,
between the Git panel and Git commit editor modal.

Release Notes:

the scroll anchor was nice for passive scrolling, it broke if you had
changed the overflow scroll settings.
