Description
环境
- 客户端：ZCode Desktop 3.10.1
- 系统：macOS (Apple Silicon)
复现步骤
- 新建一个会话，进行多轮对话（内容超过一屏）
- 切换到另一个会话/对话框
- 切回原会话
实际行为
视口定位在会话开头（第一条消息），需要手动滚动很久才能回到最新消息。
期望行为
恢复离开时的滚动位置；若离开时贴着底部，则定位到最新一条消息。
备注
- 短对话（内容未超一屏）可能无法复现；疑似消息列表为虚拟滚动，切换标签页时组件卸载、切回重新挂载后未恢复滚动锚点/未滚动到底部
- 相关问题：#341（长会话回复结束后视口锁死在中间位置、无法滚动到底部），可能是同一模块的滚动定位问题

Research direction
Reproduce the issue in ZCode Desktop 3.10.1 on macOS with a multi-turn conversation exceeding one screen, then switch conversations and return. Investigate the message list's virtual scrolling and how its scroll anchor is handled when the view is unmounted and remounted; compare with related issue #341. Done means returning to the previous position, or to the newest message when the user was at the bottom.
