// 打包产物冒烟检查: 验证原生模块真的被解包 + 能从 app.asar 里加载并 spawn
//
// 为什么需要单独一个脚本:
// 自测 (scripts/selftest/main.ts) 是从**源码**跑的, 用的是 pty 桩, 根本不碰 app.asar。
// 而 asarUnpack 配错这类问题 (比如 node-pty 平台包没递归解包) **只在打包产物上才暴露**,
// 而且在 Linux 上看不出来 (只需要一个 .node, Electron 能 dlopen 归档里的),
// 到 Windows 才炸 (conpty.dll / OpenConsole.exe / worker 脚本都必须是真实文件)。
//
// 用法:
//   node scripts/selftest/packaging-check.cjs [打包输出目录]
//   默认 dist-Electron/linux-unpacked (Windows 上传 dist-Electron/win-unpacked)
//
// 必须用 Electron 的 node 跑 (app.asar 只有 Electron 认):
//   cross-env ELECTRON_RUN_AS_NODE=1 electron scripts/selftest/packaging-check.cjs
