"""模拟器 32hex hdid 抓取 v7 (严格按约定 doc)。

时序(严格复刻成功案例 hook_emu_spawn_bypass.py):
  1. spawn(挂起)
  2. load bypass_msaoaid_maps_art_callsite.js  (挂起)
  3. load mask_frida_maps_only.js               (挂起)
  4. resume
  5. sleep 11
  6. load patch_guard_block_termination.js
  7. load 主 hook JS: 轮询等模块 -> hook setSafeDeviceId/getHdid/createWupDeviceInfo + SSL_write
