Sending a message while a question prompt was open left the prompt
lingering, blocked the send, or collided with the still-blocked agent
turn. Two root causes:
useSessionActivity treated pending permissions as idle but not pending
questions, so the send button became Stop during a question and Enter
queued/collided instead of sending. handleSubmit also never dismissed
the open question, stranding the session in a half-answered state.
The send path now dismisses open questions for the session subtree
(optimistic local clear so the card vanishes instantly, plus a formal
question.reject) and queues the message. The queued-message auto-send
hook then delivers it as the next turn once the rejected turn winds
down and the session returns to idle. Queueing avoids aborting the
turn, which surfaced an unwanted "running turn was stopped" notice.
Regression tests cover the no-op, subtree dismissal (root + subagent
child), and QuestionNotFoundError paths.
