This PR Fixes a loading performance regresssion inside the git graph.
The main issue is that we always acted on the received repository
events, this is good in 9 out of 10 cases except for the initial loading
phase of the git graph. This is because we invalidate the graph data
every time we receive a `GitStoreEvent::ActiveRepositoryChanged`,
`RepositoryEvent::BranchChanged` or `RepositoryEvent::MergeHeadsChanged`
event this still sounds good, but the caveat is that we receive these 3
events on initial repository loading. This happens when you start up Zed
and is getting the active repository, branch ect. from your project.
When it detects a repository/branch etc. it checks if it has been
changed and emits an event for it. This is always the case for initial
repository loading, because the active repository/branch always start as
**None**. So receive an event for these non actual changes makes the git
graph cancel its initial loading and start fetching again on every
invalidated graph data call.

We fixed this by checking the **scan_id** of the repo to check if the
repo has been initialized, if its bigger then 1 we know we need to
invalidate the data because it was a actual user change instead of a
initial loading event.

Third attempt to land this improvement: (#45577, #44273)

The previous PR didn’t work on Intel MacBooks because I made a wrong
assumption about the unified memory check. `has_unified_memory` only
tells us that the CPU and GPU share memory. It does not mean we’re
running on an Apple GPU family.

Memoryless textures are only supported on Apple GPUs. Some Intel Macs
report unified memory, but they don’t support memoryless textures, which
is why the previous change failed there.

So instead of relying on unified memory, we now explicitly check that
we’re running on an Apple GPU family before enabling memoryless
textures.

The binary search insertion scheme in `highlight_text` works fine for
small numbers of elements but does not handle large amounts of ranges
well, as that will cause constant memcpying of the latter half of the
vec. Bracket colorization tends to have a huge amount of entries though,
so this can cause massive lags on the foreground thread. The better
approach here is to just collect all elements and re-sort them once.

Release Notes:

- Reduced mini-stutters occuring due to large amount of bracket
colorization in big buffers and agent diffs

Now that this is also used for resuming, I think this is clearer what
the input is.

The original `refresh_matching_bracket_highlights` method always
performed a clear --> highlight procedure, even when the bracket
positions hadn't changed, causing the highlights to flicker. Normally,
for single quotes or brackets, the flickering area is small and hard to
notice (though visible if you pay close attention), but for Python
docstrings, the three quotes create a larger highlighted area, making
this issue much more apparent.

After fix:

Release Notes:

- Fixed bracket highlights flickering when editing inside brackets

After commit ee3f40f, the settings-related visual tests started
panicking. The settings UI code depends on MultiWorkspaces, so changing
these tests appropriately fixes the panics.

This PR updates the Mistral AI provider icon to better align with
Mistral's branding. The current icon (from 2023) is not fully aligned
with Mistral's visual identity, and this change ensures consistency and
clarity for users.

### Changes Made
- Replaced the Mistral AI provider icon with an updated design to better
reflect Mistral's branding.

### Testing
- **Manual Testing:** Screenshots have been taken to verify the visual
changes. No visual regression testing was performed since this is a
minor icon update.

- **Test Coverage:** No additional test coverage is required for this
change, as it is purely visual.

### Checklist
- [x] Added screenshots for manual testing.
- [x] Done a self-review taking into account security and performance
aspects (no impact).
- [x] Aligned any UI changes with the [UI
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist).

### Release Notes
- Updated Mistral AI provider icon to align with Mistral's branding.

### Additional Notes
- The previous icon (from 2024) was not fully aligned with Mistral's
visual identity. This update ensures consistency.
- Screenshots of the new icon are attached for review.

- Don't enable heap tracing by default since it has a large performance
impact. A separate action that records with heap tracing is available.
- Use in-memory recording rather than file recording, since the latter
seems to cause a lot of dropped stack walks.
- Don't record stack walk data for GPU events to help reduce the trace
size.

Release Notes:

- Fixed typo in stop diagnostics update tooltip.

Previously, `didChangeWatchedFiles` registrations triggered a rebuild of
a single `GlobSet` containing all file watch patterns for the language
server. This means that, each time `didChangeWatchedFiles` is
registered, the work it takes to construct the `GlobSet` increases. This
quadratic blowup caused massive lag with language servers which register
thousands of watched files (like Roslyn).

Instead, create one `GlobSet` per registration and try matching them
one-by-one each time a file watcher event is raised.

This PR updates the organization selector to also show the plan that is

For inverted diff APIs like `hunks_intersecting_base_text_range`, we
need a snapshot of the main buffer to use as context to compare hunk
anchors, convert anchors to points, etc. Previously, we were always
using a snapshot of the main buffer at the time when the diff was
calculated. This worked well for the hunks of the primary `BufferDiff`,
but it's not valid when the diff also has a secondary set of hunks,
because those hunks are recalculated on their own schedule--so it's
possible for the hunks of the secondary diff to contain anchors that are
newer than the original buffer snapshot that was taken at the time the
primary diff hunks were last calculated. This caused a panic when using
these anchors with the original buffer snapshot.

This PR fixes the issue by using the same approach for inverted diffs as
for non-inverted diffs at the multibuffer level: we take a snapshot of
the main buffer at the time when we snapshot the diff state (including
the diff itself), guaranteeing that that snapshot will be new enough to
resolve all the anchors included in both the primary diff and the
secondary diff.

Closes ZED-54J

Release Notes:

- Fixed a panic that could occur when using the branch diff in split
view mode.

After looking around a bit, I felt like subagent wasn't the right way to
introduce this tool to the model. And with some back and forth
verification + market research, we both agreed spawn_agent was a better
name for what this tool is doing.

It still calls the right tool if you ask for a subagent, but especially
if we move these to be running in the background, spawn will be a better
name anyway.

When using the split view, if the project diff inserts excerpts for the
same buffer using two different `PathKey`s, we panic inside
`LhsEditor::update_path_excerpts_from_rhs` because of an implicit
assumption that `excerpts_for_path()` and `excerpts_for_buffer()` return
the same number of values. This PR addresses that by ignoring any
excerpts for the given buffer that have a different path key from the
provided one.

Release Notes:

- Fixed a crash when using the split diff view.

When a buffer is folded in the split diff view and then removed from the
multibuffer (via `remove_excerpts_for_path`), the block map's
`folded_buffers` set retains a stale entry for that buffer ID. Later,
when the split view syncs folded state from the RHS display map to the
LHS, it tries to look up the companion mapping for this stale buffer and
fails because the companion no longer tracks a buffer that's been
removed from the multibuffer.

This originally caused a panic via `.expect()`. This PR:

1. Converts the panic into graceful handling by skipping unmapped
buffers.
2. Actively removes stale entries from `folded_buffers` so they don't
persist as ghost state — ensuring that if the same buffer is later
re-added, it won't incorrectly appear as folded.
3. Adds a regression test covering the full lifecycle: fold → remove →
split → re-add → assert both LHS and RHS report the buffer as not
folded.

Release Notes:

- Fixed a crash in split diff view when a folded buffer was removed and
re-added.
