Auto already allows most of what a session does, so the prompts it did
raise were mostly the interruption without the choice -- and on a phone
each one is a round trip to a question card. Measured rather than
assumed: a haiku session spawned this way ran a bare `echo` and a
`sleep` loop with no prompt at all.
The stricter modes stay one tap away in the same picker, which is where
a session that warrants one picks it.
