Grouped emoji reactions, npub search, notification fix, dev logger

- Emoji reactions now display as grouped pills (❤️5 🤙3 🔥2) instead
  of a single aggregated count. Multi-reaction per note supported.
- Throttled reaction fetch queue (max 4 concurrent) prevents relay overload.
- Searching a bare npub/nprofile navigates directly to that profile.
- Notification poller waits for relay connection before first fetch,
  fixing empty results on startup.
- Dev-only debug logger (src/lib/debug.ts) — silent in production builds.
