Show every change on the current branch relative to its base in the
Changed/Staged/Last turn dropdown. The base comes from the branch's
reflog record or an explicit per-branch user choice (persisted), never
a main/master guess; when git has no record the user picks a base once
from a searchable branch list.
- server: GET /api/git/branch-base (reflog-derived base),
GET /api/git/range-files (name-status -z with rename/copy
destination paths and -C copy detection)
- shared UI: optional getBranchBase/getGitRangeFiles runtime APIs
with boundary parsing; persisted per-branch overrides keyed by
runtime+directory+branch
- DiffView: branch scope with confirmed-unavailability coercion of
persisted tabs (detached HEAD, default-branch checkout, metadata
settled without a default), range-invalidated diff cache guarded
against stale completions, bounded branch-metadata retry, read-only
diff actions in branch scope; hidden in VS Code
- helper module branchDiffScope.ts with tests for coercion,
availability, race conditions, and retry exhaustion
