feat(assistant): the model offers the follow-up questions that fit the conversation

Browse Source 
A turn may end on suggest_follow_ups: the server answers the call itself, keeps
its questions as data-trek-follow-ups and the chat shows them as chips under
the answer. Without them the chips fall back to what the answer holds, now by
the kind of change: a tour asks about the tour, the day plan's questions only
follow a change to the day plan, and an answer that asks the user something
offers no "tell me more".
