Subject: feat: add relay server and test client

Server (cmd/relay):
- gRPC server on :50051 (configurable)
- SQLite database (default: relay.db)
- Graceful shutdown on SIGTERM/SIGINT

Test client (cmd/testclient):
- Generates key
- Publishes event
- Queries events back

Build:
- make build (relay)
- make build-client (test client)
- make build-all (both)
