/**
 * 手动 drop-in 插件后登记到 assets/addons/index.json（可选）
 *
 * 场景：从另一个 admin 项目拷贝 assets/addons/{key}/ 到目标站点。
 * 运行时也会在登录后根据后端已安装插件 + 菜单自动探测 index.js，不强制依赖本脚本。
 *
 * 用法：
 *   node scripts/register-addon.cjs <addon-key> [deploy-dir]
 * 示例：
 *   node scripts/register-addon.cjs sd_minsu
 *   node scripts/register-addon.cjs sd_minsu "D:/path/to/public/admin"
