+/* app_process + APK: CoreStartup на настоящем Android main looper и JNI worker, без Activity/профиля приложения.
+ * Аргумент — новый /data/local/tmp/utun-startup-audit-<id>/profile. Внешние подключения отключены.
+ * Компилировать как friend module приложения; nativeStop вызывается напрямую, frontend audio/video здесь не создаются. */
