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

+"""抓"一帧"dfpReport(含响应 actionV)—— 自动重试, 直到拿到为止。
+
+目标:每一台干净模拟器, 抓到一帧完整 dfpReport wire + 对应的 606B 响应(actionV),
+即获得这台"设备"的纯 Python 可重放身份凭证。App 存活 3-6s 足够(dfpReport 启动即发)。
