bug(assistant-ui): 在图表密集的 present_openui 串流渲染过程中出现间歇性的"最大更新深度超出"错误

Describe the bug

during long or chart-heavy present_openui streaming renders, React trips its infinite-update limiter. the console logs Maximum update depth exceeded (twice per occurrence), the thrown variant of the same error is caught by the integration's error boundary, so the ErrorFallback banner renders inside the assistant message and the tail of the streamed interface is truncated (in the run below, the last takeaway item's body is cut off mid-render).
