Real-Time & WebSockets

Priority: P1 (OPERATIONAL)

Workflow: Add Real-Time Feature

1. Choose protocol — WebSocket for bi-directional (chat, collab); SSE for uni-directional (feeds, notifications).
2. Implement gateway or SSE — Create @WebSocketGateway() or @Sse() controller.
3. Add auth — Validate JWT in handleConnection() for WebSocket; use standard guards for SSE.
4. Scale — Add @socket.io/redis-adapter for multi-pod WebSocket; use HTTP/2 for SSE.
5. Test connections — Verify WebSocket handshake auth rejects invalid tokens; confirm SSE streams data.
