/**
 * 把领域服务运行时（ant-copilot 的 esbuild 打包产物）同步进插件包。
 *
 * 为什么随插件分发而不是 npm 安装：`@ringoarch/ant-copilot` 发在私有 Gitea registry 上，
 * 匿名 GET 包元数据返回 401 —— 走 npm 路线等于要求每个同事机器上都配一个 Gitea token。
 * 打包产物本身是自包含单文件（依赖全内联），把它放进插件包即可做到「装插件 = 拿到运行时」。
 *
 * 用法：
 *   node scripts/sync-runtime.mjs                 # studio + writer
 *   node scripts/sync-runtime.mjs studio          # 只同步指定插件
 *   ANT_COPILOT_DIR=~/Dev/ant/ant-copilot node scripts/sync-runtime.mjs
 *
 * 前置：源仓库已构建（`npm run build:mcp` → dist/deta-mcp.mjs）。
 * 产物：plugins/<插件>/runtime/dist/deta-mcp.mjs + plugins/<插件>/runtime/manifest.json
 *   manifest 记录来源版本/提交/大小/sha256 —— 供启动器与 install-runtime 自校验（防拷错、防陈旧）。
