docs(huya): 模拟器存活闪退诊断报告与 Frida 探测脚本证据

- 诊断报告: attach 主进程静默退出/EGL 崩溃, 仅约 4s 窗口可抓帧 - scripts: attach/spawn/hook/emu 系列 Frida 脚本与抓帧/验证工具 - evidence: identity/reqchain/frame/inputbuf/magic_buf/propedge 抓取样本, emu_* 存活对比, diag_* 策略实验, baseline 裸测基准

+"""模拟器 attach 版 dfpReport 捕获 (轮询重启 attach, 覆盖冷启动窗口)。
+
+App 在模拟器上 spawn 会 EGL 崩, 所以用 attach。但 attach 只能抓 attach 之后的请求,
+而 dfpReport 在冷启动早期就发。解法: 脚本后台反复 attach, 若 App 重启则重新 attach,
+每次保住最长的 hook 窗口。配合外部 force-stop 重启 App 来完整覆盖。
