- Remove final_output from tool definitions, dispatch, and misc tools - Update system prompts to request summaries as regular markdown text - Remove print_final_output from UiWriter trait and all implementations - Remove final_output handling from agent core logic - Rename final_output_summary → summary in session continuation - Delete final_output test files - Update tool count tests (12→11, 27→26) This allows LLM summaries to stream through the markdown formatter for a more natural, responsive user experience instead of buffering everything into a tool call.
