//! Where a turn's final answer goes when it is written back to the chat.
//!
//! `complete_response` overwrites the last assistant row with the final
//! answer whenever an intermediate text arrived earlier in the turn. That is
//! only correct when no tool group ran after that row. If tools ran after it,
//! the overwrite moves the answer above those tools, and the fold then hides
//! it inside the working-out group. The answer must instead be a new row
//! after the tool groups.
