ci(retag/deploy): 增加镜像内容校验，防止静默部署旧/损坏镜像

retag_skipped_image.sh 加固:
- 源镜像 layers 有效性检查（layers=0 拒绝 retag）
- 镜像创建时间审计（>72h 输出警告）
- digest 审计记录，方便溯源

ci_staging_deploy.sh 加固:
- pull 后逐服务校验镜像 layers 有效性
- 记录每个镜像的 digest/size/created
- 对比上次部署 manifest，标注变化状态
- 写入 deploy-manifest.json 供下次对比
- 校验失败直接阻断部署

concurrency 保持 cancel-in-progress: true（不变）
生产发版链路不动
