- Dockerfile：alpine 安装 wget；加 HEALTHCHECK（/v1/health 探测，
interval 15s、start_period 20s、retries 3）
- docker-compose.yml app：
· stop_grace_period 30s（配合 fiber ShutdownWithContext 10s
+ cron 任务收尾，避免 SIGKILL 截断在途请求）
· restart unless-stopped
· json-file logging：单文件 50MB、保留 5 个滚动文件
· 业务日志卷 ./logs:/app/logs
- docker-compose.yml postgres：同样配 restart + logging
- logs/ 目录用 .gitkeep 保留；.gitignore 加 logs/* + !logs/.gitkeep
- README 新增'一键部署（docker compose）'整章：3 步上线、启动顺序图、
healthcheck 说明、优雅停机、日志、回填历史、生产 checklist
所有 12 条守卫保持无输出；build / vet 干净。
