core/cli: drop the go-to-terminal button and ring the bell when a popup goes out

"Go to terminal" promised something no desktop can do — raise another
application's window — and the popup's own close button does as much, so it
was a third button that answered nothing. `REVIEW` leaves the answer
vocabulary; a click on the body (the platform's default action) or a close
still withdraws the notification and leaves the prompt waiting.

The bell now rings as the notification is shown. A prompt is only announced
after `grace_seconds` of nobody answering it, so the human is at some other
window — possibly another virtual desktop, where a popup is easy to miss — and
the terminal's bell is the only portable cue that says where to look. It rings
once per announcement; withdrawing the popup afterwards stays silent.
