A turn blocked on a question never reaches finish 'stop', so in sorted
render mode the model's text was classified as justification and the
inline-text deferral rule hid it inside the collapsible Activity group
until the turn completed — with a pending question that never happens,
leaving the context produced before the question invisible (OpenCode
shows it inline). Keep text inline for messages that contain a question
tool part: exclude them from justification classification and from the
sorted-mode text deferral.
