Jure e3ba3dbcee Add SQLite note and profile cache (roadmap #3) ...

- Rust: rusqlite (bundled) with WAL mode; wrystr.db in app data dir
  - db_save_notes: upsert batch of raw event JSON, prune to 500 kind-1 notes
  - db_load_feed: return N most-recent kind-1 raws for instant startup display
  - db_save_profile / db_load_profile: cache NDKUserProfile JSON by pubkey
  - Falls back to in-memory SQLite if the on-disk open fails
- src/lib/db.ts: typed invoke wrappers; all errors silenced (cache is best-effort)
- feed store: loadCachedFeed() populates notes before relay connects;
  loadFeed() merges fresh+cached (so relay returning fewer notes doesn't
  erase cached ones), then saves fresh notes to SQLite
- useProfile: reads SQLite cache to show avatar/name instantly while
  relay request is in-flight; saves result to SQLite after relay responds
- Feed: calls loadCachedFeed() first → notes visible before relay connects
