Store the two-digit WS id (colored when stderr supports color, plain otherwise) in the ASGI scope state so user code can include it in its own log lines via websocket.state.logid. Move terminal helpers (use_color, strip_ansi, display width) into a new dependency-free fastapi_vue.tty module, absorbing termwidth.py, to keep imports one-directional and avoid the logging/accesslog cycle.
