- Fix metrics: change MessagesTotal, ConnectionsTotal, DisconnectionsTotal from Gauge to Counter with proper _total naming convention - Fix broadcast write-error handling: failed clients now get properly removed with accurate metrics updates - Add graceful shutdown: SIGINT/SIGTERM handling with 10s timeout, CloseGoingAway frame sent to clients before disconnect - Add integration tests: 11 tests using real WebSocket connections covering connect, broadcast, disconnect, concurrency, and shutdown - Fix example client port: changed from 8000 to 8443 to match config - Rewrite README.md to reflect current features and usage - Add AGENTS.md and .agents/summary/ documentation for AI assistants
