feat: 添加swarms团队编排功能并优化agent委派系统

- 引入AgentTeamOrchestrator支持多agent协同任务执行
- 增加第三方swarms库依赖并配置git协议替换以改善包管理
- 扩展DelegationManager支持团队任务调度和进度跟踪
- 实现中文bigram分词算法提升中文任务检索准确性
- 调整A2AClient和DelegationManager超时时间从30秒增至600秒
- 优化AgentRunResult状态判断逻辑增加有意义摘要检测
- 修改Dockerfile配置npm仓库镜像地址和git协议映射
- 更新CLI命令行接口支持网关端口配置传递
- 调整提供者超时配置机制增强请求稳定性
- 移除过时的support_group字段简化agent描述符结构
- 增强错误处理和进度事件报告机制改进用户体验
