Read #121601 Pick up a Lab task

These issues and fixes address a bug where enabling show_reasoning caused answers from separate-field reasoning models to be buffered and dumped all at once rather than streamed in real-time. The fixes involve closing the reasoning display at the right moment and resolving an associated streaming deadlock in the CLI.
