说明:
  进入维护模式，校验并发布 api-server 单文件，更新 current 链接，重启 systemd 服务并执行 readiness 检查。
  默认先停止、启动并验活唯一 BgFilter worker，再重启 API、外部生成 worker controller 和已加载的 worker 实例。
  --bgfilter-worker-health-url 缺省时从已校验的 worker env HOST/PORT 派生；显式传入时必须与父子 env 三方一致，否则预检失败。
  随包 worker systemd unit 按 --current-link 与各 env 参数渲染后安装（与 provision 同语义），自定义路径不会被打回模板默认值；默认参数下渲染输出与模板一致。
  若传入 --database，会在重启前把 GENARRATIVE_SPACETIME_DATABASE 写入 api-server 环境文件，避免服务继续读取旧库。
  若发布包包含 pingora-gateway，或传入 --require-pingora-gateway，部署脚本会要求 release manifest、二进制与 checksum 一致，再在 current 链接切换后先复核 systemd/env 仍是本机高端口 shadow 配置，启动或重启 Pingora 影子服务并复核 active。
  默认在 readiness 通过后退出维护模式；传入 --keep-maintenance-mode 时保留维护文件，供人工验收后再恢复公网。
  current 链接切换前失败时会退出本次打开的维护模式；current 链接切换后失败时保留维护模式，避免暴露半发布版本。
