feat(mobile): hh launcher + direnv auto-host for Termux/Fairphone
Add a single `hh` launcher (host/join/web/status/stop + operator passthrough) and a direnv snippet so `cd`-ing into a project dir auto-hosts a room named after it. Verified live on the Fairphone: two rooms coexist on port-scoped tmux windows (manual :8799 + direnv :8801), status health-checks each via curl (ss/netstat are unreliable on Android), stop-all tears down cleanly. Termux notes baked in: no /usr/bin/env (invoke via the `hh` alias, not the shebang); status enumerates operator daemons under $TMPDIR/hh-bridge.
