feat: 新增 Docker 部署支持、Swoole/Octane 集成及相关优化
- 添加 Dockerfile 与多套 docker-compose 配置（开发/生产环境） - 集成 Laravel Octane (Swoole) 提升性能 - 新增健康检查、监控脚本及部署文档 - 新增 Docker 镜像离线导入包（MySQL/Redis/Meilisearch） - 优化文档转换、预览服务及队列任务 - 添加 CreateAdminUser 命令与路由健康检查接口 - 新增 Swoole 队列兼容性测试套件 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
