Add `operator web` — a stdlib-only http.server shim over the control
socket so a phone browser can drive a room: message bubbles, live
long-poll updates, roster, and a real text box (GET /, /api/events,
/api/status, POST /api/say). Solves the Termux input gap where the
tmux `read --wait` loop is read-only. Binds 127.0.0.1 by default since
the socket grants room-send.
