/**
 * Gives the terminal back when the caller stops waiting.
 *
 * A prompt mounts an Ink app and resolves when a person answers it; neither is
 * reachable from outside, so an aborted run would otherwise leave the app on
 * screen and the promise pending forever.
 *
 * **Detach when the prompt settles.** `clear()` writes an erase sequence to
 * stdout, so a listener left attached past a normal answer wipes whatever is on
 * screen the next time the run aborts — in a session that keeps its transcript
 * in scrollback, that is the conversation. A run holding one signal across
 * several prompts would also stack a listener per prompt, and erase once each.
 *
 * @returns the detach, which is safe to call more than once and when no signal
 *   was given.
