fix(runtime): report an open agent question as blocked to tui-idle waits (#24533)

OpenCode's question tool (and Pi/OMP ask tools and custom modals) put the
hook row in a waiting state but paint no dialog wording the blocked-text
layer knows, so the hook lane read the wait as pending and the tui-idle
wait timed out with no blocked reason. For agents whose hooks are
authoritative, a wait the hook reports with no recognised dialog text now
blocks with the existing agent-interactive-prompt reason, unless input
reached the pane after the row (it may have answered the question before
the next hook arrived).
