- 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.

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

This PR makes the `Buffer::apply_ops` method infallible for
`text::Buffer` and `language::Buffer`.
We discovered that `text::Buffer::apply_ops` was only fallible due to
`apply_undo`, which didn't actually need to be fallible.
Release Notes:
- N/A
I noticed that scrolling the assistant panel was very slow in debug
mode, after running a completion. From profiling, I saw that it was due
to the buffer's `is_dirty` and `has_conflict` checks, which use
`edits_since` to check if there are any non-undone edits since the saved
version.
I optimized this in two ways:
* I introduced a specialized `has_edits_since` method on text buffers,
which allows us to more cheaply check if the buffer has been edited
since a given version, without some of the overhead involved in
computing what the edits actually are.
* In the case of `has_conflict`, we don't even need to call that method
in the case where the buffer doesn't have a file (is untitled, as is the
case in the assistant panel). Buffers without files cannot be in
conflict.
Release Notes:
- Improved performance of editing the assistant panel and untitled
buffers with many edits.
This adds a new action to the editor: `editor: toggle git blame`. When
used it turns on a sidebar containing `git blame` information for the
currently open buffer.
The git blame information is updated when the buffer changes. It handles
additions, deletions, modifications, changes to the underlying git data
(new commits, changed commits, ...), file saves. It also handles folding
and wrapping lines correctly.
When the user hovers over a commit, a tooltip displays information for
the commit that introduced the line. If the repository has a remote with
the name `origin` configured, then clicking on a blame entry opens the
permalink to the commit on the code host.
Users can right-click on a blame entry to get a context menu which
allows them to copy the SHA of the commit.
The feature also works on shared projects, e.g. when collaborating a
peer can request `git blame` data.
As of this PR, Zed now comes bundled with a `git` binary so that users
don't have to have `git` installed locally to use this feature.

We were seeing non-deterministic behavior in randomized tests when
generating backtraces took enough time to cause transactions to group
in some cases, but not group in others.
Tests will need to explicitly opt into grouping if they want it by
setting the interval explicitly. We have tests in the text module that
currently test the history grouping explicitly, but I'm not sure
it's needed elsewhere.
* Moving the logic from Rope to text::Buffer makes it easier
to keep the Rope in sync with the fragment tree.
* Removing carriage return characters is lossier, but is much
simpler than incrementally maintaining the invariant that
there are no carriage returns followed by newlines. We may
want to do something smarter in the future.

These completions don't supply a range that should be overwritten, so
the client needs to infer it via substring matching.

This is required because, after joining, we want to be able to refer
to operations that have happened prior to joining, which are not
captured by the state. There is probably a way of reconstructing operations
from the state, but that seems unnecessary and we've already talked about
wanting to have the server store operations rather than state once we start
persisting worktrees.
Also, use env_logger consistently in the tests for each crate.
Only initiallize the logger at all if some RUST_LOG env var is set.

If the transaction was nested, we return None. Otherwise we return the transaction id in preparation for editors to maintain their own selection state.
