"""全生命周期人工滑动监控 (GBK 安全, 无 emoji)。

Phase 1: 等 KwaiWebViewActivity 出现 (= 验证码弹起). 最多等 APPEAR_TIMEOUT 秒.
         若一直不出现 => 该号在新设备上没触发验证码 (可能直接发短信 / 号码被放行).
Phase 2: 验证码已弹起 => 记基线 photo md5, 提示人工滑动. 监听:
           - 活动离开 KwaiWebViewActivity => PASS (result=1, 人工手指过 => 自动化被检测, 非号码标记)
           - 检测到拖动后图片 md5 变化 (新缺口) 但仍在验证码页 => REFRESH (350014/350002)
           - 超时 => 无明确结果 (可能远错位静默回弹 / 没滑)
