Subject: feat: implement NIP-01 compliant Nostr relay

- WebSocket-based relay using tokio-tungstenite
- Full NIP-01 protocol support (EVENT, REQ, CLOSE)
- Event validation (signature and ID)
- In-memory event storage
- Filter support (IDs, authors, kinds, since/until)
- Configuration via environment variables
- Nix flake for reproducible builds
- Test automation script

All 6 NIP-01 smoke tests passing (100%)
