Defer createMessagesList tree walk from render-time to action-time. Previously, every rendered message eagerly computed the full message chain on every history change, even though FloatingButtons only uses it when the user selects text and triggers an action.
Changed the messages prop to a getMessages getter function that is called lazily only when an action is actually invoked.
