Add archive relay query augmentation and access-based GC (v0.45.0)

- Add async archive relay querying (local results immediate, archives in background)
- Add query caching with filter normalization to avoid repeated requests
- Add session-deduplicated access tracking for events
- Add continuous garbage collection based on access patterns
- Auto-detect storage limit (80% of filesystem) when ORLY_MAX_STORAGE_BYTES=0
- Support NIP-50 search queries to archive relays

New environment variables:
- ORLY_ARCHIVE_ENABLED: Enable archive relay query augmentation
- ORLY_ARCHIVE_RELAYS: Comma-separated archive relay URLs
- ORLY_ARCHIVE_TIMEOUT_SEC: Archive query timeout
- ORLY_ARCHIVE_CACHE_TTL_HRS: Query deduplication window
- ORLY_GC_ENABLED: Enable access-based garbage collection
- ORLY_MAX_STORAGE_BYTES: Max storage (0=auto 80%)
- ORLY_GC_INTERVAL_SEC: GC check interval
- ORLY_GC_BATCH_SIZE: Events per GC cycle
