DanConwayDev ee17a1703b feat: Add git repository archival and background cleanup ...

Archive git repositories before deletion:
- Create tar.gz archives in .archive/<npub>/<identifier>-<timestamp>.tar.gz
- Store metadata JSON with deletion info and expiry timestamp
- Archive git data BEFORE moving events to holding database
- Uses flate2 for gzip compression and tar crate for archive creation
- Graceful error handling (deletion continues even if archival fails)

Background cleanup task:
- Spawned as tokio task in main.rs
- Runs on startup (catch-up for offline periods)
- Runs at configurable interval (default: 24 hours)
- Deletes expired events from holding database
- Removes archive tar.gz files and metadata JSON
- Tracks disk space reclamation in CleanupResult

Archive metadata structure:
- Deletion timestamp and event ID
- Maintainer pubkey and repository identifier
- Archive file path for cleanup coordination
- Expiry timestamp (deletion_ts + retention_secs)

Tests: 21 tests covering:
- Archive unit tests (8 tests)
  - Archive creation and compression
  - Extraction and integrity verification
  - Metadata serialization
  - Error handling (missing directories, corrupt data)
- Cleanup unit tests (5 tests)
  - Expired event deletion
  - Archive file cleanup
  - Missing file handling
  - CleanupResult statistics
- Integration tests (8 tests)
  - End-to-end archival workflow
  - Background cleanup with short retention (5 seconds)
  - Startup cleanup (pre-existing expired data)
  - Disk space reclamation verification
  - Multiple expired events
  - Preservation of non-expired events
