{#
    TIR (Tool-Integrated Reasoning) Chat Template - 单轮格式
    用于 Qwen3 Thinking 模型的 TIR 训练和推理
    
    特性:
    - 支持 system/user/assistant 角色（无独立 tool 角色）
    - assistant 消息自动添加 <think> 开始标签
    - 工具调用和响应内联在 assistant 内容中：
      <think>
      推理...
      <tool_call>
      ...
      </tool_call>
      <tool_response>
      ...
      </tool_response>
      继续推理...
      </think>
