1. 增加对 Wenxin 的内建联网能力
2. 补齐 Wenxin 及 Hunyuan 的引用来源适配
3. 启用 Qwen 流式工具调用

Wenxin
Hunyuan

Note:

1. 百度给个调用文档不完整，需要到示例代码中心中获取完整参数

{
  "enable": false,
  "enable_citation": false,
  "enable_trace": false
}

2. 启用 enable_trace 后， Wenxin 流头部会参入 search_results 信息，看下后续如何适配 已适配

data: {"id":"as-kqd1t7j73a","object":"chat.completion.chunk","created":1740848970,"model":"ernie-4.0-8k-latest","choices":[{"index":0,"delta":{"content":"今天是**","role":"assistant"},"flag":0}],"search_results":[{"index":1,"url":"https://news.cctv.cn/news/china/index.shtml","title":"中国新闻_央视网(cctv.com)"},{"index":2,"url":"http://chinahoy.com.cn/","title":"今日中国"},{"index":3,"url":"https://www.chinanews.com.cn/china/?q=nnurm","title":"中国新闻网_时政"}]}

4. 启用 search_info 后，Hunyuan 流会在每一个 Chunk 中引入 search_info.search_results 信息

这个输出模式应该就和 pplx 的一样，和这段逻辑类似：

lobe-chat/src/libs/agent-runtime/utils/streams/openai.ts

Lines 129 to 147 in a76d2bf

	if (typeof content === 'string') {
	// in Perplexity api, the citation is in every chunk, but we only need to return it once
	if ('citations' in chunk && !!chunk.citations && !streamContext?.returnedPplxCitation) {
	streamContext.returnedPplxCitation = true;
	const citations = (chunk.citations as any[]).map((item) =>
	typeof item === 'string' ? ({ title: item, url: item } as CitationItem) : item,
	);
	return [
	{ data: { citations }, id: chunk.id, type: 'grounding' },
	{ data: content, id: chunk.id, type: 'text' },
	];
	}
	return { data: content, id: chunk.id, type: 'text' };
	}
	}

只需要做个判断在这组 chunk 里是否包含有 search_results 数组，然后 return 的时候同时return grounding 和 text 即可。

[
    { data: { citations }, id: chunk.id, type: 'grounding' },
    { data: content, id: chunk.id, type: 'text' },
]

@arvinxx 已适配，顺带把 Hunyuan 的引用也一起搞掉了

@arvinxx has been adapted, and Hunyuan's quotation was also removed
