- 新增部署脚本模板，服务器地址与账号改为读取本地配置或环境变量

deploy.example.mjs

+/**
+ * 构建并上传到服务器
+ *
+ * 服务器信息取自 deploy.config.mjs（已加入忽略，不会入库），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
