ROOG 8c4ad80dab main: 引入 AgentProvider 流式事件与 OpenAI 兼容适配
- 增加流式事件流支持,Provider 输出 `message.delta` 等事件
- 实现 OpenAI 兼容适配器,包括 RequestBuilder、ApiClient 等模块
- 更新 Agent Run 逻辑,支持流式增量写入与模型完成状态管理
- 扩展配置项 `agent.openai.*`,支持模型、密钥等配置
- 优化文档,完善流式事件与消息类型说明
- 增加单元测试,覆盖 Provider 和 OpenAI 适配相关逻辑
- 更新环境变量与配置示例,支持新功能
