- Reduce ping detection window from ~45s to ~15s (pingTimeout 5s, pingInterval 10s)
- Listen to window offline/online events for instant UI feedback on network drop
- Force immediate reconnect on online event instead of waiting for backoff
- Fix stuck-reconnecting bug when network returns within ping timeout window
- Wrap on/off/emit in useCallback to prevent listener re-registration every second
- Expose reconnectCount to trigger revalidator.revalidate() after each reconnect
- Reset hasConnectedOnce ref per socket instance to avoid spurious revalidations
- Remove stale socket ref from hook return value; add emit helper instead
