本次更新聚焦修复流式输出重复问题。我们在后端流式桥接层新增了增量归一化机制，可识别并过滤累计片段、重发片段和边界重叠片段，确保前端仅接收真实新增内容。修复范围已覆盖 Eino 单代理、Deep、Plan-Execute、Supervisor 以及原生 ReAct 全链路，并通过测试与 lint 校验。
This update focuses on resolving duplicate content in streaming responses. We added delta normalization in the backend streaming bridge to detect and filter cumulative chunks, retransmitted chunks, and overlap-boundary fragments, ensuring the frontend receives only true incremental output. The fix now covers Eino Single Agent, Deep, Plan-Execute, Supervisor, and native ReAct end-to-end, and has been validated with tests and lint checks.
