Also, on macOS, in order to actually have callstack frames properly
recorded by Tracy, you need to manually run `dsymutil` on the binary.

When viewing a branch diff (e.g., 'Changes since origin/main'), the
toolbar was hidden because `ProjectDiffToolbar` filters for
`DiffBase::Head` only. This meant users couldn't send review comments to
the Agent panel from the branch diff view.
Now there's a new `BranchDiffToolbar` which:
- Only activates for branch diff views (`DiffBase::Merge`)
- Shows only the 'Send Review to Agent' button (not stage/unstage
controls)
- Only appears when there are review comments (same behavior as the
existing toolbar)
(No release notes because this is still feature-flagged.)

Happy New Years! This PR is a second take at
https://github.com/zed-industries/zed/pull/38127 (cc @ConradIrwin)
This PR is significantly less complicated than the last attempt: while
we still keep our data on the `NavigationHistory` object, we no longer
tightly integrate it with the existing back/forward "browser history."
Instead, we keep our own stack of `(origin, target)` pairs (in a struct
to make it easy to extend with e.g., tag names in the future).
The PR is split into two separable commits. Most of the implementation
is in the second commit, which:
- Defines the stack data structure
- Implements `pane::GoToOlderTag` and `pane::GoToNewerTag` in terms of
the stack
- Hooks into `navigate_to_hover_links` to push tag stack entries
This last bit is the most fiddly. The core challenge is that we need to
keep track of the `origin` location and calculate the `target` location
across three codepaths that might involve creating a new editor and/or
splitting the pane. One thing in particular I found difficult was that
an editor's `nav_history` (an `ItemNavHistory`) seems to be populated
asynchronously. Instead of relying on it, I decided in this code to make
my own `ItemNavHistory`. I briefly tried to refactor the code in
question, but it seemed like it would significantly increase the scope
of the change.
I prefer this all-in-one tracking centered around
`navigate_to_hover_links ` to the `start/finish` approach taken in
https://github.com/zed-industries/zed/commit/aebd394fb60641a2dd32b1f1b76a7c79ec4aa2ea
because I find it easier to convince myself that the right data is being
populated at the right times. Of course, let me know if you think
there's a better solution.

Adds a very simple diff review button behind a feature flag, which
appears in the gutter of people who have the flag (currently just me;
it's not even enabled for staff, since it doesn't do anything yet).
Mostly this PR just adds the feature flag, the button, and tests.
Release Notes:
- N/A
This happens when a user's default branch has different remote and local
versions on their system. Because we would get a diff using just a
branch name without including it's remote name as well
This is a better default because it's far less confusing from a user's
perspective to debug what's going on.
Release Notes:
- git: Fix BranchDiff showing incorrect diffs when default local branch
is out of sync with the remote default branch
The tree view effectively always sorts by status, not by path.
Release Notes:
- Fixed incorrect ordering of paths in the project diff when using the
git panel's tree view.
Breadcrumb visual reorchestration which makes a couple of key changes:
- Breadcrumbs are now displayed in file headers for multibuffer views.
Singleton buffers are unchanged.
- Multibuffer views now have collapse/expand all buttons available in
the toolbar
- Search in multibuffer views now takes up less space, by occupying the
primary toolbar location erstwhile taken up by breadcrumbs

This PR reworks the (still feature-gated) side-by-side diff view to use
a different approach to representing the multibuffers on the left- and
right-hand sides.
Previously, these two multibuffers used identical sets of buffers and
excerpts, and were made to behave differently by adding a new knob to
the multibuffer controlling how diffs are displayed. Specifically, the
left-hand side multibuffer would filter out the added range of each hunk
from the excerpts using a new `FilteredInsertedHunk` diff transform, and
the right-hand side would simply not show the deleted sides of expanded
hunks. This approach has some problems:
- Line numbers, and actions that navigate by line number, behaved
incorrectly for the left-hand side.
- Syntax highlighting and other features that use the buffer syntax tree
also behaved incorrectly for the left-hand side.
In this PR, we've switched to using independent buffers to build the
left-hand side. These buffers are constructed using the base texts for
the corresponding diffs, and their lifecycle is managed by `BufferDiff`.
The red "deleted" regions on the left-hand side are represented by
`BufferContent` diff transforms, not `DeletedHunk` transforms. This
means each excerpt on the left represents a contiguous slice of a single
buffer, which fixes the above issues by construction.
The tradeoff with this new approach is that we now have to manually
synchronize excerpt ranges from the right side to the left, which we do
using `BufferDiffSnapshot::row_to_base_text_row`.

Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

Closes#35803
This PR adds tree view support to the git panel UI as an additional
setting and moves git entry checkboxes to the right. Tree view only
supports sorting by paths behavior since sorting by status can become
noisy, due to having to duplicate directories that have entries with
different statuses.
### Tree vs Flat View

#### Architecture changes
Before this PR, `GitPanel::entries` represented all entries and all
visible entries because both sets were equal to one another. However,
this equality isn't true for tree view, because entries can be
collapsed. To fix this, `TreeState` was added as a logical indices field
that is used to filter out non-visible entries. A benefit of this field
is that it could be used in the future to implement searching in the
GitPanel.
Another significant thing this PR changed was adding a HashMap field
`entries_by_indices` on `GitPanel`. We did this because `entry_by_path`
used binary search, which becomes overly complicated to implement for
tree view. The performance of this function matters because it's a hot
code path, so a linear search wasn't ideal either. The solution was
using a hash map to improve time complexity from O(log n) to O(1), where
n is the count of entries.
#### Follow-ups
In the future, we could use `ui::ListItem` to render entries in the tree
view to improve UI consistency.
Release Notes:
- Added tree view for Git panel. Users are able to switch between Flat
and Tree view in Git panel.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

This PR does two related things:
- First, it gets rid of the undifferentiated `RepositoryEvent::Updated`
in favor of three new events that have clearer definitions:
`BranchChanged`, `StashEntriesChanged`, and `StatusesChanged`. An
implication of this is that we no longer emit a `RepositoryEvent` unless
some git state changed; previously we would emit `RepositoryUpdated`
after doing a git status scan even if no statuses changed.
- Second, it changes the subscription strategy of the project diff to
make it update more robustly. Previously, the project diff only
subscribed to the `GitStore`, so it relied on getting a `GitStoreEvent`
when some buffer's diff hunks changed, even if the git status of the
buffer's file didn't change (e.g. a second hunk in a file that was
already modified). After this PR, it also subscribes to the individual
`BufferDiff` entities for buffers that have a git status, so the
`GitStore` is freed from that responsibility. This also fixes some real
cases where the previous strategy was not effective in keeping the
project diff up to date (captured in a test).
Release Notes:
- Fixed some cases where the project diff would fail to update in
response to git events.
Closes#39172
This refactors when we resolve UI keybindings in an effort to reduce
flickering whilst painting these: Previously, we would always resolve
these upon creating the binding. This could lead to cases where the
corresponding context was not yet available and no binding could be
resolved, even if the binding was then available on the next presented
frame. Following that, on the next rerender of whatever requested this
keybinding, the keybind for that context would then be found, we would
render that and then also win a layout shift in that process, as we went
from nothing rendered to something rendered between these frames.
With these changes, this now happens less often, because we only look
for the keybinding once the context can actually be resolved in the
window.

Also reduced cloning in the keymap editor in this process, since that
requiered changing due to this anyway.
Release Notes:
- Fixed some cases where keybinds would appear with a slight delay,
causing a flicker in the process
We were spawning the process on the foreground thread before which can
block an arbitrary amount of time. Likewise we no longer block
deserialization on the terminal loading.

Fixes the `Open Diff` action for untracked files when the `sort_by_path`
setting is enabled. The `ProjectDiff` wasn't correctly moving the
multibuffer's cursor to the untracked file because, when that setting is
enabled, it's sort prefix is changed to the tracked files sort prefix, and that
wasn't accounted for in `move_to_entry`.
Before these changes, the `sort_prefix` field for `PathKey` was called `namespace`, it was renamed to be clearer what its purpose is.

This fixes a regression in #39557--for the project diff, we rely on
getting an event when a path inside a git repository changes, even if
the git state of the repository didn't change as a result (e.g. a new
modification to a file that already had the "modified" status).
I've also changed this code to send the `UpdateRepository` proto message
even when the git state didn't change, since otherwise we have the same
problem in SSH and collab projects.

We have unnecessary clones for the fields here as most of the snapshots

The ordering of path-based excerpts in multibuffers regressed with
#38744, because we changed the `path` field of `PathKey` to be a string
(from `std::path::Path`) and used the derived `Ord` implementation,
which doesn't agree with the path-based order of worktree traversals.
This PR fixes that by using `RelPath` for `PathKey`. Instead of using
`File::full_path`, which can be absolute, we always use `File::path` and
distinguish different worktrees using their ID.

Closes https://github.com/zed-industries/zed/issues/38690Closes#37353
### Background
On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.
Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.
### Solution
Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.
The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
