let items = thread_manager.list_collaboration_modes();

Make collaboration mode list honor thread feature overrides

list_collaboration_modes always returns presets from ThreadManager's startup config. But thread/start can override features.default_mode_request_user_input per thread, so the returned developer_instructions can contradict that thread’s real request_user_input availability. If a client reuses these instructions (non-None), normalize_turn_start_collaboration_mode won’t rewrite them, leaving stale guidance in prompts.

Superseded by #12735 so the active PR uses branch collaboration-modes-config.
