This PR reworks how Zed calculates diff num stats by moving the
calculation to the `RepositorySnapshot` layer, instead of the
`GitPanel`. This has a couple of benefits:
1. Snapshot recalculations are already set up to recompute on file
system changes and only update the affected files. This means that diff
stats don't need to manage their own subscription or states anymore like
they did in the original PR.
2. We're able to further separate the data layer from the UI. Before,
the git panel owned all the subscriptions and tasks that refreshed the
diff stat, now the repository does, which is more inline with the code
base.
3. Integration tests are cleaner because `FakeRepository` can handle all
the data and calculations of diff stat and make it accessible to more
tests in the codebase. Because a lot of tests wouldn't initialize the
git panel when they used the git repository.
4. This made implementing remote/collab support for this feature
streamline. Remote clients wouldn't get the same buffer events as local
clients, so they wouldn't know that the diff stat state has been updated
and invalidate their data.
5. File system changes that happened outside of Zed now trigger the diff
stat refresh because we're using the `RepositorySnapshot`.
I added some integration tests as well to make sure collab support is
working this time. Finally, adding the initial diff calculation to
`compute_snapshot` didn't affect performance for me when checking
against chromium's diff with HEAD~1000. So this should be a safe change
to make.
I decided to add diff stats on the status entry struct because it made
updating changed paths and the collab database much simpler than having
two separate SumTrees. Also whenever the UI got a file's status it would
check its diff stat as well, so this change makes that code more
streamlined as well.

Closes#41832
Extends https://github.com/zed-industries/zed/pull/19455
When an internal `.editorconfig` is detected in the worktree, we
traverse parent directories up to the filesystem root looking for
additional `.editorconfig` files. All discovered external configs are
loaded and cached (shared when multiple worktrees reference the same
parent directories). When computing settings for a file, external
configs are applied first (from furthest to closest), then internal
configs.
For local projects, file watchers are set up for each external config so
changes are applied immediately. When a project is shared via collab,
external configs are sent to guests through the existing
`UpdateWorktreeSettings` proto message (with a new `outside_worktree`
field). SSH remoting works similarly.
Limitations: We don't currently take creation of new external editor
config files into account since they are loaded once on worktree add.
Release Notes:
- Added support for `.editorconfig` files outside the project directory.
Zed now traverses parent directories to find and apply EditorConfig
settings. Use `root = true` in any `.editorconfig` to stop inheriting
settings from parent directories.
This PR removes the database schema migrations from the repo, as these
are now managed by Cloud.
There's a new `20251208000000_test_schema.sql` "migration" that we use
to create the database schema for the tests, similar to what we use for
SQLite.
