Fix TDZ race condition in fetchEvent timeout handler (#368)

* fix: resolve TDZ race condition in fetchEvent timeout handler

The timeout callback on line 1060 could fire before the subscription
assignment on line 1065, causing a Temporal Dead Zone error when
accessing 's.stop()'. This race condition was discovered when malformed
nostr entities triggered the 10-second timeout.

Changed s.stop() to s?.stop() to safely handle the case where the
timeout fires before subscription assignment completes.

* chore: bump to beta.63
