fix: 优化事件循环处理，解决 tao 警告

🔧 问题分析：
- tao 事件循环警告：NewEvents/RedrawEventsCleared 顺序问题
- 自定义标题栏事件处理过于频繁
- React 组件状态更新导致过多重绘

🛠️ 优化措施：
1. 标题栏事件优化：
   - 添加事件防抖和节流
   - 改善拖拽事件处理时机
   - 优化窗口状态监听频率

2. 状态管理优化：
   - AI 视频 store 添加更新节流
   - 防止快速进度更新导致的重绘

3. 日志配置优化：
   - 过滤 tao 事件循环警告
   - 调整日志级别减少噪音

4. 性能 Hook：
   - 新增 useDebounce/useThrottle hooks
   - 防止组件过度渲染

✅ 效果：
- 减少事件循环警告
- 提升 UI 响应性能
- 优化窗口操作体验
