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

+内置自动重试(EGL 偶发崩 + 反调试偶发), 一旦抓到 dfpReport+actionV 或达上限即停。
