feat: implement agent coordination foundation (Week 1)
✅ Multi-Agent Communication Framework - Implemented comprehensive communication protocols - Created hierarchical, P2P, and broadcast protocols - Added message types and routing system - Implemented agent discovery and registration - Created load balancer for task distribution - Built FastAPI application with full API ✅ Core Components Implemented - CommunicationManager: Protocol management - MessageRouter: Advanced message routing - AgentRegistry: Agent discovery and management - LoadBalancer: Intelligent task distribution - TaskDistributor: Priority-based task handling - WebSocketHandler: Real-time communication ✅ API Endpoints - /health: Health check endpoint - /agents/register: Agent registration - /agents/discover: Agent discovery - /tasks/submit: Task submission - /messages/send: Message sending - /load-balancer/stats: Load balancing statistics - /registry/stats: Registry statistics ✅ Production Ready - SystemD service configuration - Docker containerization - Comprehensive test suite - Configuration management - Error handling and logging - Performance monitoring 🚀 Week 1 complete: Agent coordination foundation implemented!
