- A reconnect while an install runs keeps the login it started with; a new
one from ~/.ssh/config applies after.
- Frame > Open SSH goes through the server, so it uses the same headset and
address as the app and refuses when there's none.
- A bare frame alias in use when a headset is set up stays selectable.
