Instagram自动滚动Reels功能失效，请求代码修复支持

问题分析 #

之前的尝试存在几个关键问题：

• 未导入Keys模块，导致send_keys(Keys.ARROW_DOWN)无法执行
• 通过page_source判断reelViewer存在的方式不可靠，页面动态渲染时容易出现误判
• 等待条件设置不合理，没有准确监听视频播放状态
• 未处理登录后可能出现的弹窗（如保存登录信息提示）

代码关键说明 #

• 导入Keys模块：解决之前无法发送键盘按键的问题
• 处理登录弹窗：自动跳过"保存登录信息"提示，避免后续操作受阻
• 视频状态监听：通过JavaScript获取视频的duration和currentTime，准确判断视频是否播放完毕，替代不可靠的页面源码判断
• 稳定切换逻辑：视频播放接近结束时才执行向下滚动，确保切换时机准确，同时添加短暂等待保证下一个Reel加载完成
