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

+"""模拟器版 dfpReport 捕获: 验证全新模拟器是否为"新设备身份"。

+连接 127.0.0.1:31878 (模拟器 frida 15.2.2), spawn 方式。
+只 hook SSL_write, 抓 dfpReport 请求 + 对应 606B 响应(内含 actionV/真或新 hdid)。
+若 attach/反调试, 用 bypass 三件套 (可选开关)。
