fetch-depth: 2 is too shallow — a batch push of 10 commits (like
Phase 1-6 commit chain) leaves github.event.before outside the
fetched range, so git diff returns empty and nothing deploys.
- Set fetch-depth: 0 (full history) so diff always has a reachable
base.
- Added git cat-file -e check: even with full history, force-pushes
or orphan base SHAs trigger a "deploy all" fallback instead of
silently skipping.
