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.
Bind sockets ourselves and pass them to uvicorn (Server.serve(sockets) or the
ChangeReload/Multiprocess supervisors, same API uvicorn.run uses). localhost
expands to 127.0.0.1 and ::1 so clients reach the server regardless of how
localhost resolves; individual bind failures degrade with a warning. Reload
mode now serves all endpoints instead of only the first, multi-endpoint
configs no longer run lifespan twice, and unix sockets are cleaned up on
exit.
run() gains access_log (default on) and log_config parameters. When
enabled, uvicorn's own access log is disabled (access_log=False) and
replaced by an ASGI middleware (adapted from the uvicorn access-log
branch) that logs colored request lines, WebSocket open/close pairs,
and pre-accept rejections in open format.
log_config dicts (uvicorn's default or user-supplied) are patched
best-effort via a registered patch pipeline in fastapi_vue.logging:
swapping in our AccessFormatter, routing our output to a private
fastapi_vue.access logger (uvicorn gates its protocol-level access
logging on uvicorn.access.hasHandlers(), so that logger must stay
handlerless), and filtering stock WebSocket handshake chatter from
uvicorn.error. Non-dict or structurally unexpected configs pass
through untouched.
The middleware is installed by patching Config.load/load_app, hooked
into AccessFormatter instantiation so reload/worker subprocesses
(which re-apply log_config without re-calling run()) are covered.
