WebSocketStream — legacy bridge between the EventBus and WebSocket clients.

NOTE: The real broadcasting is now done in backend/main.py via
`_ws_broadcast` which properly awaits the async send. This class is kept
for backward compatibility with the api.py facade, but its `attach_bus`
method is a no-op (the actual wiring happens in main.py).
