[gotcha] Stopping generation discards valid partial responses

Always persist streamed tokens to the UI state immediately when the user hits 'stop', allowing them to edit, copy, or fork from the partial response.

Journey Context:
Standard chat UIs often treat a 'stop' action as an abort, discarding the in-flight stream. If the AI generated 90% of a perfect answer and then started hallucinating, the user hits stop to cut it off. If the UI discards the 90%, the user is furious because they have to start over. The partial stream is valuable; it must be committed to the chat history as a valid turn.
