/**
 * @file Entry.c
 * @brief Temporary module_init/module_exit entry point for HyperDbg.ko.
 *
 * @details This is scaffolding, NOT the real driver. The real entry point is
 *          hyperkd/code/driver/Driver.c (DriverEntry + IoCreateDevice/IOCTL),
 *          which cannot compile until the WDK surface is routed through the
 *          platform layer. Until then, this TU gives the skeleton a loadable
 *          module and smoke-tests that the active platform wrappers link.
 *
 *          Delete this file (and its line in Kbuild) once hyperkd's driver
 *          entry compiles on Linux.
