We need more fetch depth here for the check, hence bumping this.
Also does a drive-by cleanup of the checkout step within xtask to make
this (hopefully) more intuitive to use.

not read Username for 'https://github.com'`)
- related Linear issue: BIZOPS-853
## Testing
- ruby -e "require 'yaml';
YAML.load_file('.github/workflows/background_agent_mvp.yml')"

Before this PR we wouldn't always serialize workspaces when a
mutliworkspace adds/removes a workspace. This PR fixes this by adding a
test and calling serialization in remove

Add `remove_worktree()` and `rename_worktree()` to the `GitRepository`
trait with `RealGitRepository` implementations that shell out to `git
worktree remove/move`.
Implement all 4 worktree methods (`worktrees`, `create_worktree`,
`remove_worktree`, `rename_worktree`) on `FakeGitRepository` backed by
`FakeGitRepositoryState`, with `simulated_create_worktree_error` for
test-time fault injection.
Add `set_create_worktree_error()` helper on `FakeFs`.
Add `parse_worktrees_from_str` helper and 7 new tests covering real git
operations and fake worktree lifecycle.

Release Notes:
- Improved the behavior of the `vim: join lines` and `editor: join lines`. Comment and other language specific line prefixes are now stripped from the join line
Switches `newline_below` from adding a newline to the start of the next
line in a multibuffer, to appending a newline at the end of the
selections current lines. This keeps the insertion within the excerpt of
the selection rather than adding a newline to the excerpt below.

Add Kanayago as an available Ruby language server in default settings.
Disabled by default (prefixed with `!`), users can opt-in via their
settings.
This corresponds to the extension-side support added in
zed-extensions/ruby#224.
Release Notes:
- ruby: Added Kanayago as an available language server.
Reverts the editor's paragraph navigation behavior that was changed in
#47734. Whitespace-only lines are now treated as paragraph boundaries
again for non-vim mode users.
Vim mode retains its own implementation where only truly empty lines
are paragraph boundaries.
Release Notes:
- Fixed editor paragraph navigation to treat whitespace-only lines as
paragraph boundaries again

- Improved Bedrock error messages: region-locked models ask the user to
try a different region, rate limits and access errors are reported
cleanly instead of as raw API responses
- Streamlined Bedrock model list to 39 curated models

It now creates multi-turn conversation, where first two messages are the
original teacher prompt and output.
This way, we'll have changes in teacher prompt automatically applied to
repair without having to explicitly sync them.

See https://github.com/zed-industries/notify/pull/2 for more details
Note: notify already fixed this upstream, and I'm planning on using
their crate as our dependency once their v9 is officially released.
Release Notes:
- Fix panic that could occur when navigating external code
## Summary
- add a new crash issue-linking subagent prompt
(`.factory/prompts/crash/link-issues.md`)
- add a scheduled/manual GitHub workflow for week-one background-agent
runs (`.github/workflows/background_agent_mvp.yml`)
- add Sentry candidate selection script to rank top crashes by
solvability × population (`script/select-sentry-crash-candidates`)
- add a local dry-run runner for end-to-end MVP execution without
push/PR actions (`script/run-background-agent-mvp-local`)
## Guardrails in this MVP
- draft PRs only (no auto-merge)
- reviewer routing defaults to: `eholk,morgankrey,osiewicz,bennetbo`
- pipeline order is: investigate -> link-issues -> fix
## Validation
- `python3 -m py_compile script/select-sentry-crash-candidates
script/run-background-agent-mvp-local`
- `python3 script/select-sentry-crash-candidates --help`
- `python3 script/run-background-agent-mvp-local --help`

Our strategy for keeping excerpts in sync between the two sides of the
split diff is generally
- mutate the excerpts on the RHS
- pull out the new excerpts for the affected path from the RHS
- translate those ranges to the LHS
- update the LHS excerpts with those ranges
But this can break down when the translated ranges overlap on the LHS
despite the original ranges not overlapping on the RHS. This can happen,
for example, when a large deletion in a file crosses several excerpt
boundaries. It's rare because normally excerpt boundaries in the project
diff and branch diff are adjusted to keep entire diff hunks in view, but
we defer this for dirty files, so it's not hard to trigger it when using
the agent or editing an individual file while the diff is open in
another tab.
Release Notes:
- Fixed a panic that could occur when editing files while the project
diff or branch diff was open.

Closes#49172
- Fixes a regression on X11 where content size was divided by the scale
factor twice after the wgpu migration, causing half-sized rendering on
HiDPI screens.
- Aligns X11 [content_size()] behavior with Wayland by returning logical
pixel bounds directly.

This PR removes some code left over from how we used to do impersonation
for local development.
The local development impersonation path is separate now, so we don't
need all of this plumbing in Collab.

This PR adds a button in the Git Panel to open the `git: branch diff`
view. The button only shows if the staging area is clean/no changes and
if the branch is not main/master. I've been using this action so much
these days and we should expose it on the UI so it's more discoverable.

This change improves performance of project diff in that:
* scrolling in split view for very large diffs (think chromium repo with
`git reset HEAD~1000`) is now very smooth on macOS and fairly smooth on
Linux
* switching from split to unified is very smooth on macOS, and fairly
smooth on Linux
There still remains the case of (severe) hangs when switching from
unified to split however, but it will be addressed in a follow-up PR.
Anyhow, here's the screenshot of the Instruments.app capture of opening
chromium repo in Zed in split view, scrolling a little, moving to
unified, scrolling some more, and moving back to split. Prior to this
change, split -> unified would cause a severe hang, whereas now it's a
hang and thus feels much smoother already (without Instruments profiling
is barely visible). Unified -> split severe hangs are still there but
don't last as long.

diffs/repositories.
