Previously, staging a large file in the git panel would block the UI
items until that operation finished. This is due to the fact that
staging is a git op that is locked globally by git (per repo) meaning
only one op that is modifying the git index can run at any one time. In
order to make the UI snappy while letting any pending git staging jobs
to finish in the background, we track their progress via `PendingOps`
indexed by git entry path. We have already had a concept of pending
operations however they existed at the UI layer in the `GitPanel`
abstraction. This PR moves and augments `PendingOps` into the model
`Repository` in `git_store` which seems like a more natural place for
tracking running git jobs/operations. Thanks to this, pending ops are
now stored in a `SumTree` indexed by git entry path part of the
`Repository` snapshot, which makes for efficient access from the UI.
Release Notes:
- Improved UI responsiveness when staging/unstaging large files in the
git panel
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).

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

This is another in the series of PRs to make the GitStore own all
repository state and enable better concurrency control for git
repository scans.
After this PR, the `RepositoryEntry`s stored in worktree snapshots are
used only as a staging ground for local GitStores to pull from after
git-related events; non-local worktrees don't store them at all,
although this is not reflected in the types. GitTraversal and other
places that need information about repositories get it from the
GitStore. The GitStore also takes over handling of the new
UpdateRepository and RemoveRepository messages. However, repositories
are still discovered and scanned on a per-worktree basis, and we're
still identifying them by the (worktree-specific) project entry ID of
their working directory.
- [x] Remove WorkDirectory from RepositoryEntry
- [x] Remove worktree IDs from repository-related RPC messages
- [x] Handle UpdateRepository and RemoveRepository RPCs from the
GitStore

This adds a new version of the project diff editor to go alongside the
new git panel.
The basics seem to be working, but still todo:
* [ ] Fix untracked files
* [ ] Fix deleted files
* [ ] Show commit message editor at top
* [x] Handle empty state
* [x] Fix panic where locator sometimes seeks to wrong excerpt

When a file exists in HEAD, is deleted in the index, and exists again in
the working copy, git produces two lines for it, one reading `D `
(deleted in index, unmodified in working copy), and the other reading
`??` (untracked). Merge these two into the equivalent of `DA`.
Release Notes:
- Improved handling of files that are deleted in the git index but exist
in HEAD and the working copy
The output of `git status --porcelain=v1` includes untracked
directories, i.e. directories that have no tracked files beneath. Since
we have our own way of computing a "summary" status for each directory
in a repo, this is not helpful for Zed; and it interferes with our
handling of nested repos. So just skip these lines in the output.
Closes#23133
Release Notes:
- Fix project panel colors when one git repository is nested beneath
another
- [x] Basic implementation
- [x] Disable commit buttons when committing is not possible (empty
message, no changes)
- [x] Upgrade GitSummary to efficiently figure out whether there are any
staged changes
- [x] Make CommitAll work
- [x] Surface errors with toasts
- [x] Channel shutdown
- [x] Empty commit message or no changes
- [x] Failed git operations
- [x] Fix added files no longer appearing correctly in the project panel
(GitSummary breakage)
- [x] Fix handling of commit message

To prepare for the introduction of folding in the git panel, these
codepaths need to work with the canonical source of all git status
entries, not just the ones that are visible in the panel.

First, parse the output of `git status --porcelain=v1` into a
representation that can handle the full "grammar" and doesn't lose
information.
Second, as part of pushing this throughout the codebase, expand the use
of the existing `GitSummary` type to all the places where status
propagation is in play (i.e., anywhere we're dealing with a mix of files
and directories), and get rid of the previous `GitSummary ->
GitFileStatus` conversion.
- [x] Synchronize new representation over collab
- [x] Update zed.proto
- [x] Update DB models
- [x] Update `GitSummary` and summarization for the new `FileStatus`
- [x] Fix all tests
- [x] worktree
- [x] collab
- [x] Clean up `FILE_*` constants
- [x] New collab tests to exercise syncing of complex statuses
- [x] Run it locally and make sure it looks good

This PR continues work on the feature flagged git panel.
Changes:
- Defines and wires up git panel actions & keybindings
- Re-scopes some actions from `git_ui` -> `git`.
- General git actions (StageAll, CommitChanges, ...) are scoped to
`git`.
- Git panel specific actions (Close, FocusCommitEditor, ...) are scoped
to `git_panel.
- Staging actions & UI are now connected to git!
- Unify more reusable git status into the GitState global over being
tied to the panel directly.
- Uses the new git status codepaths instead of filtering all workspace
entries

Add `/auto` behind a feature flag that's disabled for now, even for

We've decided on a different design for context inference, but there are
parts of /auto that will be useful for that, so we want them in the code
base even if they're unused for now.

***Update**: after rebasing on top of
https://github.com/zed-industries/zed/pull/16915/ (that also changed how
search worked), the results are still good, but not 10x. Instead of
going from 10s to 500ms, it goes from 10s to 3s.*
This improves the performance of project-wide search by an order of
magnitude.
After digging in, @as-cii and I found that opening buffers was the
bottleneck for project-wide search (since Zed opens, parses, ... buffers
when finding them, which is something VS Code doesn't do, for example).
So this PR improves the performance of opening multiple buffers at once.
It does this by doing two things:
- It batches scan-requests in the worktree. When we search, we search
files in chunks of 64. Previously we'd handle all 64 scan requests
separately. The new code checks if the scan requests can be batched and
if so it, it does that.
- It batches `git status` calls when reloading the project entries for
the opened buffers. Instead of calling `git status` for each file, it
calls `git status` for a batch of files, and then extracts the status
for each file.
(It has to be said that I think the slow performance on `main` has been
a regression introduced over the last few months with the changes made
to project/worktree/git. I don't think it was this slow ~5 months ago.
But I also don't think it was this fast ~5 months ago.)

I realized that somehow, the `git` executable is able to compute `git
status` much more quickly than libgit2, so I've switched our git status
logic to use `git`. Follow-up to
https://github.com/zed-industries/zed/pull/12266.
Release Notes:
- Improved the performance of git status updated when working in large
git repositories.
