prepare_review_repo is best-effort, but the system prompt unconditionally
told the agent the repo is checked out at the PR head. On a reused sandbox,
a dirty worktree (or a transient fetch failure) makes 'git checkout <sha>'
fail; prep returns False, the old checkout stays in place, and the reviewer
confidently reads stale code — observed as 'I rechecked the current head'
replies quoting pre-push code.
- checkout with --force so leftover worktree state can't block it, verify
HEAD matches the requested sha, tolerate 'git fetch --all' failures
- when prep fails, the prompt now warns the checkout may be stale and tells
the agent to re-fetch/checkout (or fall back to API file contents) before
trusting local files

* feat: prep reviewer repo at init and load repo skills
Clone + checkout the PR head during reviewer agent init so SkillsMiddleware
can discover the repo's .agents/skills and .claude/skills from disk at its
one-shot scan, and so the LLM no longer narrates the clone mid-run.

* fix: load reviewer skills from trusted base sha and fetch PR pull ref
Address review findings: skills are now extracted from the PR base sha via
git archive into a dir outside the checkout (prevents PR-authored SKILL.md
prompt injection), and repo prep fetches refs/pull/<n>/head with a strict
checkout so fork PRs fail loudly instead of silently reviewing the default
branch.
* fix: drop ref from skill-extraction log to satisfy CodeQL
