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.
