/**
 * 部署模板：构建并上传到服务器
 *
 * 用法：复制本文件为 deploy.mjs（已加入忽略，不入库），再创建 deploy.config.mjs
 *      填写服务器信息，然后执行 pnpm run deploy
 *
 * 服务器信息取自 deploy.config.mjs，缺该文件时回落到环境变量
 * DEPLOY_HOST / DEPLOY_USER / DEPLOY_PORT / DEPLOY_TARGET
 *
 * 前置：SSH 免密登录（只需一次）
 *   1. 没有 %USERPROFILE%\.ssh\id_rsa 就先 ssh-keygen -t rsa 回车到底
 *
 *   2. 拷贝公钥到服务器（会提示输一次服务器密码）：
 *      Windows: type %USERPROFILE%\.ssh\id_rsa.pub | ssh root@server "cat >> ~/.ssh/authorized_keys"
 *      Mac:     ssh-copy-id root@server
 *
 *   3. ssh root@server 不弹密码直接连上即成功
