Subject: feat: add gRPC handler with event validation and publishing

Handler implementation:
- EventStore interface (consumer-side)
- Server with PublishEvent, QueryEvents, CountEvents, PublishBatch
- pb.Event <-> nostr.Event conversion helpers
- Signature and ID validation using existing nostr package
- Canonical JSON generation for storage
