- 配置版本：fsutil 版本化备份（内容相同自动去重），主 nginx.conf 与 VPS vhost 的版本列表/逐行差异/一键回滚，回滚先校验语法与 nginx -t 再写回 - agent 0.12.2：写 vhost 前留版本；nginx -t 校验失败改为恢复上一个可用版本（此前直接删文件），新增域名 vhost 版本端点，双架构二进制已重编 - 通知：补企业微信 / 钉钉 / 飞书机器人，切换预设时服务地址跟随该预设默认值 - 阈值告警：新增 internal/monitor 巡检（CPU/内存/磁盘持续超阈值、隧道连续 N 次未注册），默认关闭，带静默期与恢复通知 - API Token：api_tokens 表 + Authorization Bearer 认证，只读/读写两种范围；令牌管理与改密/退出仅限登录会话
