- 新增 Seg_Server_Docker 自包含部署内容，包含前后端、FastAPI、Celery、PostgreSQL、Redis、MinIO、演示视频和 DICOM 数据。 - 保留 demo 数据以支持恢复演示出厂设置，排除 SAM 2.1 .pt 权重并在 README 中补充下载命令。 - 补充 GPU 部署、backend/worker 镜像复用、frpc/frps + NPM 公网域名反代部署说明。 - 在 .env/.env.example 中用 # XXXX 标注局域网和公网域名部署需要修改的配置项。 - 添加部署分支 .gitignore，忽略本地模型权重、构建产物、缓存和日志。
