pub fn hand_over(store: &Questions, q: &mut Question)Expand description
Record that the agent has read everything so far, so the daemon waiter does not resume a session to tell it what was already printed.
Callers must invoke this only after the word reached the agent’s stdout: marking first would let a tool timeout kill the process between the mark and the print, and the waiter would then consider a word delivered that no agent ever saw.
