/* Deshab SDK 驱动入口模板
 *
 * 由 scaffold/new-module.ps1 生成时自动替换:
 *   {{MODULE_NAME}}  -> 驱动名 (如 mydriver)
 *   {{CLASS}}        -> DKM_CLASS_* 类别 (如 DKM_CLASS_MISC)
 *   {{STAGE}}        -> 加载阶段 0-3
 *
 * 展示最小 DKM 驱动框架: driver_desc + driver_init + driver_exit。
 * 构建方式: clang -c main.c -> ld.lld -r -o {{MODULE_NAME}}.drv main.o
 * (见 scaffold/driver/build.ps1 片段或 build.ps1 的 Build-DkmDriver)
