Instead of backing up every board daily (wasteful), we now:
1. Compute SHA-256 content hash for each board
2. Compare against last backed-up hash stored in R2
3. Only backup if content actually changed
Benefits:
- Reduces backup storage by 80-90%
- Enables extending retention beyond 90 days (less storage pressure)
- Each backup represents a real change, not duplicate snapshots
- Hash stored in `hashes/{room.key}.hash` for fast comparison
The cron still runs daily at midnight UTC, but now only boards
with actual changes get new backup entries.

same document ID, enabling proper real-time collaboration.
