/**
 * Windows 安装后资源 tar 解压脚本
 *
 * 由 NSIS installer.nsh 的 customInstall 宏调用。
 * 通过 LobsterAI.exe (ELECTRON_RUN_AS_NODE=1 模式) 执行。
 *
 * 用法: LobsterAI.exe <本脚本路径> <tarPath> <destDir>
 *
 * 效果:
 *   输入: $INSTDIR/resources/win-resources.tar
 *   输出: $INSTDIR/resources/cfmind/, SKILLs/, python-win/
 *   tar 文件由 NSIS 脚本在解压后删除
 *
 * 依赖: 从 app.asar 内加载 tar npm 包 (Electron 内置 ASAR 透明读取支持)
