fix(chat): persist reasoning for Responses stream and WS final snapshot

- Parse reasoning_summary_text (and related) SSE events in OpenAI Responses
  streaming; forward deltas to on_token and return reasoning_content on
  LLMResponse so thinking-mode rows get event_payload in the store.
- When emitting chat/final from turn_runner, include event_type/event_payload
  and merge reasoning_content from earlier assistant rows in the same
  turn_uuid so the collapsed reasoning fold matches what streamed.
