Adds a "gitdiff" block, opened from the terminal context menu, that lists the changed files in the terminal's git repo and shows each file's diff against HEAD with the Monaco diff viewer. Files can be reverted from the list after confirmation. Git runs through new Remote* RPCs on the connection's wsh server, so the view works for local, SSH and WSL connections. Repo-relative paths from the client are validated so file reads and reverts cannot escape the repo. Diff models now keep the file's own extension in their URI so Monaco can infer the language, which also gives the AI file diff viewer syntax highlighting.

WalkthroughThe change adds backend Git status, file-diff, and file-revert operations and exposes them through remote RPCs. It adds a Git Diff block that polls repository status, displays changed files and diffs, and supports confirmed reverts and inline-diff toggling. A terminal menu action opens the block. The change also adds preview fixtures and tests for Git operations and view utilities. Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to Switching repositories during a pending revert can briefly disrupt the new Git Diff view. This is a bounded issue, but the revert response should be guarded. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)
✨ Finishing Touches🧪 Generate unit tests (beta)

Review comments at @frontend/app/view/gitdiff/gitdiff-model.ts:
- Around line 180-190: Update the post-request guard in refresh to discard
results when the current cwd or connection route no longer matches the values
captured before the await; only apply status and reconcile selection when the
request still belongs to the current repository.
Review comments at @frontend/app/view/gitdiff/gitdiff-util.ts:
- Around line 1-8: Update GitDiffView’s reconcileSelection logic to call
loadFileDiff for the selected file on each poll, even when its status signature
is unchanged; remove the signature-based early return while preserving the
existing selection checks.
Review comments at @frontend/app/view/gitdiff/gitdiff.tsx:
- Around line 40-74: Make the file row that invokes onSelect focusable and
keyboard-operable, with button semantics and Enter/Space activation. Update the
revert button that invokes onRevert so it becomes visible on keyboard focus, and
add a visible focus indicator; preserve its existing click behavior.
Review comments at @pkg/util/gitutil/gitutil_test.go:
- Around line 295-296: Check setup-operation errors in the relevant gitutil
tests: fail immediately if `os.MkdirAll` or `os.WriteFile` fails, and check the
`os.Remove` that modifies the mixed-repository fixture. Remove the unnecessary
outside-file setup from `TestGetFileDiffRejectsEscape`, since `GetFileDiff`
rejects the path before filesystem access.
Review comments at @pkg/util/gitutil/gitutil.go:
- Around line 401-433: Update RevertFile to verify the current Git status of
data.Path before deleting it when data.Status is GitStatus_Untracked. Use the
existing porcelain status parsing to confirm the path is still untracked, and
refuse deletion if it is tracked, changed, missing from the status output, or
otherwise does not match; retain the existing filesystem checks and removal for
confirmed untracked files.
- Around line 177-197: Update validateRepoPath to resolve repoRoot and
fullPath’s parent through symlinks before returning fullPath, then verify the
resolved parent remains within the resolved repository root. Return an error if
resolution fails or the parent escapes; retain the existing lexical containment
checks.

- Discard status results for a cwd/connection that changed mid-request - Refetch the selected diff on every poll so same-count edits are not stale - Make file rows and the revert button keyboard accessible - Resolve symlinked parents when validating repo paths - Re-check that a file is untracked before deleting it on revert - Use literal pathspecs for git commands and check test fixture errors

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winGuard the pending revert against target changes.
revertFilecaptures the old target but does not validate it after the RPC. If the connection or working directory changes while the RPC is pending, a failure can write the old error into the new target, and a success can clear the new target's diff when both files use the same path. Add the same target guard used byrefreshbefore both state updates.Suggested fix

pkg/util/gitutilpackage plus three RPCs on the connection's wsh server (RemoteGitStatusCommand,RemoteGitFileDiffCommand,RemoteGitRevertFileCommand). Because of this, the view works on local, SSH and WSL connections. Git runs withGIT_OPTIONAL_LOCKS=0so polling doesn't contend with the user's own git commands..orig/.mod, so Monaco could never infer a language.
