// 官方插件集中构建:一次进程构建所有官方插件 + 生成清单,产物进 dist/(已 gitignore)。
// 官方插件目录本身不各自安装依赖:统一从本目录 node_modules 解析 SDK(nodePaths)。
// CI(publish-plugins.yml)把 dist/ 强推到 plugins-dist 分支,前端经 jsDelivr 远程拉取。
// 本地自测:`npm install && npm run build`,再把 VITE_PLUGIN_REGISTRY_URL 指向本地 dist。

// 版本不在这里写死 —— 从各插件的 package.json 读取(单一真源),
// 与插件 src 里 definePlugin({version}) 保持一致,避免清单与产物版本脱节。
