配置了Qwen3-32B的thinking模型，但是模型输出中reasonning_content字段没有内容

在coze上使用Qwen3模型，reasoning_content字段没有内容输出，但是自己通过http接口调用的时候有结果

Start by tracing how Coze configures Qwen3-32B thinking models and maps their responses to the reasoning_content field; the issue names no file or test entry point. Compare this behavior with the reporter’s direct HTTP result, and consider the issue done when reasoning_content is populated for the configured model.
