huangzhenting 717af46606 feat: Vue UI 增强 — 统计/筛选联动、自动跟随、交互优化
- 新增 getVueStats(since?)/apiGetVueStats/GET /api/vue/stats,供 Vue UI 专用
  SQLite 模式走数据库全量聚合+since过滤,getStats() 保持原样不影响 HTML 版本
- Vue UI 所有 /api/stats 调用改为 /api/vue/stats
- SSE stats 事件改为调 statsStore.load() 从 /api/vue/stats 拉最新数据
- 时间筛选增加 1小时/6小时选项,状态筛选改为 emoji 图标风格
- 状态筛选选中态:全部用蓝紫渐变底色,图标按钮用对应颜色边框+文字
- AppHeader/RequestList 缩写处全面补充 title tooltip
- 新增「自动跟随」功能:选中记录后可开启,SSE 推送新请求时自动切换并滚动到顶部
- 修复 ConfigDrawer draft 可能为 null 的 TS 错误
- 修复 CSS typo:.rfmt.responses background 颜色值多余空格
- upsertRequest 改用 Object.assign 避免 SSE 推送时替换对象引用打断 hover

* 核心升级:
* - 存储完整的请求参数messages, system prompt, tools
* - 存储完整的模型返回内容raw response
* - 存储转换后的 Cursor 请求
* - 阶段耗时追踪 (Phase Timing)
* - TTFT (Time To First Token)
* - 用户问题标题提取
* - 日志文件持久化JSONL 格式,可配置开关)
* - 日志清空操作
* - 全部通过 Web UI 可视化
