This PR adds a bunch of design improvements to the toolbar of (tab)
views that display diffs: the uncommitted changes, branch diff, and
agent diff tabs. This involves adjusting spacing, sizing, and other
small tweaks across all of these views, including touching up the
divider component API a little bit, adjusting Git icons design, adding
diff stat numbers to the uncommitted changes tab so its consistent with
the others, and more (e.g., moving the split buttons into its own
component to ensure they look the same across all uses). Ended up also
going on a slight de-tour to make all uses of the split button in the
Git panel consistent design-wise.
All in all, this is just tidying up the design of all of these surfaces
that are all relatively similar.

Release Notes:
- Added diff stat numbers to the uncommitted changes view.
# Objective
- Default the solo diff view to show changed hunks with excerpted
context instead of expanding the entire file.
- Closes https://github.com/zed-industries/zed/issues/59489
## Solution
- Initialize the solo diff editor with excerpts around changed hunks.
- Add a header toggle for switching between the excerpted changes-only
view and the full-file view.
- Keep both sides of the split diff visually aligned when excerpts are
collapsed.
## Testing
- `cargo check -p git_ui`
- `cargo test -p git_ui`

for viewing the full file.

# Objective
- Polish the solo diff review UI by reducing redundant controls and
hiding inactive fold controls in split diff views.
## Solution
- Collapse the solo diff header's `Stage File` / `Unstage File` actions
into one button that shows the action relevant to the file's current
staging state.
- Stop reserving fold gutter space and rendering fold crease toggles for
editors with companion snapshots, matching the existing LHS split diff
behavior.
## Testing
- `cargo fmt --check`
- `cargo check -p git_ui`

## Showcase
Before, the solo diff header showed both file-level staging actions at
once, and the RHS split diff gutter could show fold arrows that did not
work in that view. After this change, the header shows the relevant
file-level staging action and split companion panes no longer show
inactive fold controls.
Release Notes:
- Improved solo diff controls by showing the relevant file staging
action and hiding inactive fold toggles in split diffs.

This changes git panel file activation so double-clicking or
secondary-opening a changed file opens a dedicated full-file diff tab
backed by a `SplittableEditor`.
The per-file diff reuses the project diff staging and restore controls,
respects the configured diff view style, and focuses an existing
per-file diff tab when one is already open instead of creating
duplicates.
Verified with `cargo run`.
Release Notes:
- Improved git panel file diff opening.
