改动

修复短消息在原生偏好宽度与正文列宽之间反复排版，以及大字号下新流式消息未完成落位的问题。文字测量统一采用列宽；当前与上一轮先完成布局，更早历史继续按需加载，所有记录和模型上下文保留。

回看与程序滚动分开处理，生成完成和键盘变化保留阅读位置。“回到最新”进入输入区，支持旧系统惯性结束结算。短高度界面使用更宽的呈现，引用可以展开查看，草稿和语音附件保留；输入、发送和收键盘控件使用完整点击区域。

验证

• 完整原生应用回归 354 项：352 通过，2 项缺少指定本地样本而跳过。最后触控调整后重跑聊天 13 项、旁注几何 4 项及相关原生界面流程。
• 普通和真实系统夜间最大字号、三轮流式对话、第三轮结尾截图识别、重新读取较早历史、消息引用/点赞菜单均通过。
• 真实横屏有界面宽高断言。键盘前的发送区域宽高均不小于 44pt；八行草稿、展开引用、收键盘和旋转回竖屏后全文保留。初始竖屏半屏另有回归。
• 200 轮合成历史完整保留，承载场景创建 12 个原生文本控件。20 次宽度协商只测量及安装文本一次，选择保留。
• iOS 发布契约 Node 105/105、Python 11/11，固定依赖校验通过。验收文档和原生子项目截图随改动提交。

材料全部为隔离合成数据，未读取真实用户书籍或调用真实模型。实际 VoiceOver、iOS 17 运行时与物理 iPhone 尚未验收；本 PR 不包含 TestFlight 分发或版本号调整。
