feat: 修复首页滚动卡顿并添加下拉刷新功能

滚动性能优化:
- 使用ScrollView组件替代普通View,提供原生滚动性能
- 启用硬件加速:transform: translateZ(0)和will-change属性
- 优化CSS动画:减少clip-path动画频率,简化transition效果
- 图片渲染优化:image-rendering: optimizeSpeed和backface-visibility

 下拉刷新功能:
- 集成ScrollView原生下拉刷新能力
- 添加refresherEnabled、refresherTriggered等配置
- 实现handleRefresh异步刷新逻辑
- 完善错误处理和用户反馈

 性能提升措施:
- 移除不必要的transition动画减少重绘
- 使用requestAnimationFrame节流触摸事件
- 启用contain: layout style paint优化渲染
- 简化active状态效果,使用opacity替代transform

 用户体验改进:
- 流畅的原生滚动体验,消除卡顿现象
- 直观的下拉刷新操作,符合用户习惯
- 完整的加载状态和错误提示
- 自动数据同步和状态管理

 技术实现:
- ScrollView enhanced模式启用增强特性
- enablePassive被动事件监听提升性能
- refresherBackground和refresherDefaultStyle视觉定制
- 异步错误处理和Toast提示集成

解决问题:首页滚动时的卡顿现象,提升用户交互体验
