GCS check used a 72h cutoff but only listed 2 days of prefixes (~48h),
making the staleness check unreachable. Also added 1MB minimum file
size validation to match the S3 check.
Forgejo dump produces gitea-db.sql as a text SQL dump (XORM export),
not a binary SQLite file. Opening it directly with sqlite3.connect()
throws DatabaseError. Now imports the SQL dump into a temp DB first.
Fix 4 critical issues:
- Add filter/priority/deleteMarkerReplication to S3 CRR rule (deploy would fail without)
- Add stack dependency so replica deploys before main stack
- Fix DB file extension matching (.sqlite3/.sql instead of .db)
- Replace nonexistent `forgejo restore` command with actual restore steps in README
Fix 4 moderate issues:
- Add timeout=10 to Slack webhook urlopen call
- Add filter='data' to tarfile.extract for PEP 706 compliance
- Add explicit ValueError for unknown handler mode
- Use date-scoped S3/GCS prefix instead of unbounded listing
