* fix(changes-panel): scope commits/diff to live branch divergence; flatten single-repo
Two bugs in the COMMITS panel made it surface commits and file changes
that were already on main:
1. The commit list and the cumulative diff both anchored to a stale base.
Commit list used `git merge-base HEAD <local-branch>` and the file diff
used the session's stored base SHA captured once at session start. On
long-lived worktrees the local main ref lags far behind origin/main, so
the merge-base lands on an old SHA; once the agent merges main back in,
the stored base is also stale. Both end up sweeping in dozens of main
commits as if they were the branch's work.
2. `git log <base>..HEAD` follows both parents of a merge commit by
default, surfacing main commits brought in via merges from main.
Fixes:
- agentctl computes merge-base against `origin/<target_branch>` (with a
local-ref fallback for unfetched/local-only branches), and uses that
for both the commit log and the cumulative diff. Mirrors GitHub's
three-dot PR diff semantics — anchor to live divergence with the
upstream, not a session-start snapshot.
- `git log` now passes `--first-parent` so only the branch's own line of
work plus its merge commits show up; commits brought in via merges from
main are excluded.
Frontend: drop the per-repo "REPOSITORY" sub-header in the COMMITS panel
for single-repo workspaces. CommitsRepoGroup gains a `showHeader` prop;
when the workspace has one untagged group the section renders flat with
the per-repo Push / PR (and Stage all / Commit / Unstage all) buttons
lifted into the section header. Multi-repo rendering unchanged.

* fix: address PR review feedback
- Scope --first-parent to the divergence-range path only (Greptile P1).
The flag is wrong for open-ended history calls — future activity
widgets etc. need the full graph.
- Log empty merge-base case in cumulative diff (Greptile P2). Silent
fallback to stored base was invisible during diagnostics.
- Rename TestRunGitCumulativeDiffForRepo_PrefersOriginRef →
TestComputeMergeBase_CorrectAnchorForCumulativeDiff (Claude). Test
exercises computeMergeBase, not the runGitCumulativeDiffForRepo
conditional; new name reflects what it actually proves.
- Add TestGetLog_NoBaseReturnsFullGraph to lock in the --first-parent
scoping.

* fix: address PR review round 2
- Drop dead ActionButtonsSection from changes-panel-timeline.tsx (unused
export, no consumers anywhere). Brings the file from 640 → 516 lines,
comfortably under the 600-line TS limit Claude flagged.
- Extract isSingleRepoGroup helper into lib/group-by-repo.ts and use it
in all three sites (CommitsSection, FileListBody, FileListSection) so
single-repo detection has one source of truth.
