- ChatManager：
- 引入 System.Text.Json，用于将 agent thread 序列化与反序列化（示例：thread.Serialize(...) -> JsonSerializer.Deserialize -> agent.DeserializeThread）。
- 增加示例：创建 OpenAIClient、初始化 agent、运行流式响应并处理更新。
- 小幅格式和空行调整。
- AiChatService：
- 为 Agent 发送接口 PostAgentSendAsync 增加注释与路由标记 HttpPost("ai-chat/agent/send")。
注意：提交中出现了硬编码的 API Key，请尽快改为从配置或机密管理中读取以防泄露。
