8b6f3ec647 Fix the project diff sometimes missing updates (#40662)
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.

43a9368dff clock: Cleanup ReplicaId, Lamport and Global (#40600)
- Notable change is the use of a newtype for `ReplicaId`
- Fixes `WorktreeStore::create_remote_worktree` creating a remote
worktree with the local replica id, though this is not currently used
- Fixes observing the `Agent` (that is following the agent) causing
global clocks to allocate 65535 elements
- Shrinks the size of `Global` a bit. In a local or non-collab remote
session it won't ever allocate still.

83bfe2ff7b multi_buffer: Make anchor_in_excerpt fallible for bad text anchors (#40496)
`MultiBuffer::anchor_in_excerpt` currently just wraps the given text
anchor in a multibuffer anchor. This allows one to get a multibuffer
anchor that points outside its excerpt which is basically never what one
wants. This PR now does a bounds check and returns `None` if the given
text anchor is not within the bounds of the excerpt.

de8dd9bea5 Rework editors to register and query buffers on scroll (#40388)
Preparation to https://github.com/zed-industries/zed/pull/40183
Moves https://github.com/zed-industries/zed/pull/22958 further: now,
instead of selection, scrolling the buffer into view is enough to get
registered and, later, be queried for its LSP data such as inlay hints,
diagnostics and document colors.

This effectively undoes https://github.com/zed-industries/zed/pull/28855
as now we try to register whatever's visible more aggressively, instead
of implicitly via inlay hints.

Release Notes:

- Reworked editors to register and query buffers on scroll

c58931ac04 git_ui: Fix open diff for untracked files when sorting by path enabled (#39862)
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.

Closes #39529 

Release Notes:

- Fixed 'Open Diff' action for untracked files when `sort_by_path` is
enabled

aced13bc9f Fix ordering of multibuffer excerpts (#39476)
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.

- N/A

fc0b249136 multi_buffer: Fix handling of ExcerptId::max() (#38887)
This removes a hack from `MultiBuffer::anchor_at` that works around
missing logic for handling `ExcerptId::max()` by implementing that said
missing logic.

Generally, `ExcerptId::min()` is already being handled correctly due to
how `Cursor` seeking works, we tend to seek to or beyond a seek target,
meaning `min` will always match the first excerpt as expected. `max` on
the other hand will always seek beyond the last excerpt resulting in no
excerpt being found, so any code path dealing with the excerpt sumtree
will have to specially check for this special excerpt ID to work
correctly.

03f9cf4414 Represent relative paths using a dedicated, separator-agnostic type (#38744)
Closes https://github.com/zed-industries/zed/issues/38690
Closes #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).

Release Notes:

- N/A

e1b57f00a0 sum_tree: Reduce Cursor size for contextless summary types (#38776)
This reduces the size of cursor by a usize when the summary does not
require a context making Cursor usages and constructions slightly more
efficient.

This change is a bit annoying though, as Rust has no means of
specializing, so this uses a `ContextlessSummary` trait with a blanket
impl while turning the `Context` into a GAT `Context<'a>`. This means
`Summary` implies are a bit more verbose now while contextless ones are
slimmer. It does come with the downside that the lifetime in the GAT is
always considered invariant, so some lifetime splitting occurred due to
that.

e43ad858d8 Add debug methods for visually annotating ranges (#38097)
This allows you to write `buffer_snapshot.debug(ranges, value)` and it
will be displayed in the buffer (or multibuffer!) until that callsite
runs again. `ranges` can be any position (`usize`, `Anchor`, etc), any
range, or a slice or vec of those. `value` just needs a `Debug` impl.
These are stored in a mutable global for convenience, and this is only
available in debug builds.

For example, using this to visualize the captures of the brackets
Tree-sitter query:

b8c30f448f Improve Tab Map performance (#32243)
## Context

While looking into: #32051 and #16120 with instruments, I noticed that
`TabSnapshot::to_tab_point` and `TabSnapshot::to_fold_point` are a
common bottleneck between the two issues. This PR takes the first steps
into closing the stated issues by improving the performance of both
those functions.

### Method

`to_tab_point` and `to_fold_point` iterate through each character in
their rows to find tab characters and translate those characters into
their respective transformations. This PR changes this iteration to take
advantage of the tab character bitmap in the `Rope` data structure and
goes directly to each tab character when iterating.

The tab bitmap is now passed from each layer in-between the `Rope` to
the `TabMap`.

### Testing 

I added several randomized tests to ensure that the new `to_tab_point`
and `to_fold_point` functions have the same behavior as the old methods
they're replacing. I also added `test_random_chunk_bitmap` on each layer
the tab bitmap is passed up to the `TabMap` to make sure that the bitmap
being passed is transformed correctly between the layers of
`DisplayMap`.

`test_random_chunk_bitmap` was added to these layers:
- buffer
- multi buffer
- custom_highlights
- inlay_map
- fold_map

## Benchmarking 

I setup benchmarks with criterion that is runnable via `cargo bench -p
editor --profile=release-fast`. When benchmarking I had my laptop
plugged in and did so from the terminal with a minimal amount of
processes running. I'm also on a m4 max

### Results 

#### To Tab Point

Went from completing 6.8M iterations in 5s with an average time of
`736.13 ns` to `683.38 ns` which is a `-7.1875%` improvement

#### To Fold Point

Went from completing 6.8M iterations in 5s with an average time of
`736.55 ns` to `682.40 ns` which is a `-7.1659%` improvement

#### Editor render 

Went from having an average render time of `62.561 µs` to `57.216 µs`
which is a `-8.8248%` improvement

#### Build Buffer with one long line

Went from having an average buffer build time of `3.2549 ms` to `3.2635
ms` which is a `+0.2151%` regression within the margin of error

#### Editor with 1000 multi cursor input 

Went from having an average edit time of `133.05 ms` to `122.96 ms`
which is a `-7.5776%` improvement

ae54a4e1b8 Add commands to select next/previous siblings in the syntax tree (#35053)
Closes #5133 and discussion
https://github.com/zed-industries/zed/discussions/33493

This PR adds two new commands to select next/previous siblings in the
syntax tree. These commands were modelled after the existing ones about
expand/shrink selection. With this PR I've added new key bindings
inspired by `helix` for previous / next / expand / shrink selections.

- Add commands to select next/previous siblings in the syntax tree

1ae326432e Extract a scheduler crate from GPUI to enable unified integration testing of client and server code (#37326)
Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.

## Changes

- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.

## Benefits

- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.

Follows Rust guidelines; run `./script/clippy` for verification.

- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

aa1629b544 Remove some unused events (#37498)
This PR cleans up some emitted events around the codebase. These events
are either never emitted or never listened for.

It seems better to re-implement these at some point should they again be
needed - this ensures that they will actually be fired in the cases
where they are needed as opposed to being there and getting unreliable
and stale (which is already the case for the majority of the events
removed here).

Lastly, this ensures the `CapabilitiesChanged` event is not fired too
often.
