Implement a real-time game server using protobuf over WebSocket: - Protobuf schema with 14 message types in oneof Envelope - Room-based lobby with join/leave/chat broadcast - ELO-based matchmaking with expanding range (±100 to ±500) - Turn-based game session lifecycle management - Multi-stage Docker build (Alpine) - Unit tests for matchmaking and game session logic
