**问题** 切换 Session 后，`StreamingMessage` 底部的计时器会从 0 重新开始计数。根因是 `ElapsedTimer` 组件在 mount 时用 `Date.now()` 本地初始化开始时间，Session 切换导致组件 remount 后时间重置。 **修复** - `stream-session-manager` 的 `SessionStreamSnapshot` 已包含 `startedAt` 字段，记录流的真实开始时间 - 将 `startedAt` 从 `ChatView` → `MessageList` → `StreamingMessage` → `StreamingStatusBar` → `ElapsedTimer` 逐级透传 - `ElapsedTimer` 改为基于传入的 `startedAt` 计算 elapsed，组件 remount 后仍能恢复真实累计时长 **影响范围** 仅影响流式响应状态下的底部计时器显示，不改变任何持久化逻辑或计时行为。 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

已合并 🎉 根因定位 + 修法都很干净（把本来就存在的 startedAt 透传到底层就够了，不用改数据模型）。只有一个小 nit：MessageList.tsx 里 感谢贡献，下次发版带上。 |

问题描述
在侧边栏切换 Session 后再切回来，底部流式回复的计时器会从
0s重新开始计数。期望它应该基于真实的流累计时长展示，不因切换而重置。根因
ElapsedTimer在StreamingMessage.tsx里 mount 时用本地Date.now()记录开始时间。切换 Session 导致ChatView（连带StreamingMessage）unmount/remount，计时器就归零了。修复
stream-session-manager的SessionStreamSnapshot已包含startedAt字段，记录流的真实开始时间。现在把它从组件树顶层一路透传到底层：ChatView→MessageList→StreamingMessage→StreamingStatusBar→ElapsedTimerElapsedTimer改为基于传入的startedAt计算 elapsed，组件 remount 后仍能恢复正确的累计时长。改动文件
src/components/chat/ChatView.tsxstreamSnapshot.startedAt传给MessageListsrc/components/chat/MessageList.tsxstartedAtprop 并透传给StreamingMessagesrc/components/chat/StreamingMessage.tsxStreamingStatusBar/ElapsedTimer接收startedAt并基于它计算验证方式
