aichat2 emits SSE events with types like
tool_start,tool_result,text_delta, etc. The existing Nexior stream parser only readsdelta_answerandid. This PR extends the response model and stream callback to pass through all event fields, enabling the tool-calling UI components to render tool invocations in real-time.
