"""spawn + 快速加载 bypass → resume 的【存活时长】多轮测试。

验证: spawn 路径带 bypass 后 App 能活多久, 是否每个 spawn 都稳定抓到 dfpReport。
流程每轮:
  force-stop → spawn → attach → 挂起内快速加载 bypass_msaoaid + mask_frida
  → resume → 加载 patch_guard + 主hook(SSL_write抓dfp)
  → 持续观察存活, 记录死亡时间 或 抓满 N 秒
统计多轮: 平均存活时长, dfpReport 捕获成功率, actionV。
