"""
部署通知脚本（支持 Staging / Production）

与 CI 通知（ci_notify_success.py / ci_notify_failure.py）卡片格式对齐。
发送部署结果通知到飞书 webhook（卡片格式）。

支持三种状态：success / failure / rollback
支持两种环境：staging / production

用法:
    python3 deploy_notify.py --status success --detail "部署成功" --env staging
    python3 deploy_notify.py --status rollback --detail "健康检查失败，已回滚" --env production
    python3 deploy_notify.py --status failure --detail "部署过程出错" --env production --failed-step "构建镜像"
