Feature: add Docker support

[FjHe]

#63

1. Docker 配置文件（docker/ 目录）

• docker-compose.yml - 定义了三个服务的编排配置：
  • MySQL 数据库服务（包含健康检查、字符集配置）
  • 后端服务（Spring Boot 应用）
  • 前端服务（Vue + Nginx）

2. 文档里添加了docker启动说明
   docs/getting-started.md

感谢贡献，稍后我们看下

这里有对启动的容器验证吗？

仓库里没有 actuator：pom.xml 无 spring-boot-starter-actuator，代码里也没有任何 /actuator/health 或自定义 /health 端点，/actuator/health 只会 404，wget --spider 对 404 返回非零 → 容器永远 unhealthy。

[lzq986]

1、nginx.conf 的 /api/ 反代没写 proxy_buffering off，默认缓冲会把流式输出攒起来、卡顿，甚至前端"假死"；proxy_read_timeout 60s 还会把 >60s 无输出的长推理直接掐断

[lzq986]

辛苦打包好镜像后继续测试下，直接访问容器的地址来测试功能是否正常

[FjHe]

提交commit修复的内容如下：
1、health check 我还是引入了spring-boot-starter-actuator。
2、修改了流式输出情况下，nginx的几个配置
3、docker fatjar启动的情况下，agentscope-extensions-nacos-skill的依赖则必须引入了，会报缺失。
4、修改了一下描述。

之前验证了一下午感觉都好好的，这次测到这么多问题感觉自己失忆了。。
