feat(search): add Baidu Qianfan AI Search provider with i18n docs

- Add BaiduSearchConfig struct (api_key, base_url, max_results)
- Register baidu_search in WebToolsConfig and defaults (max_results: 10)
- Insert Baidu Search in priority chain: DuckDuckGo > Baidu > GLM Search
- Use perplexityTimeout (30s) — Qianfan is LLM-based and slower than standard search
- Add baidu_search example block to config.example.json

- Add Baidu Search section with config table and JSON example
- zh: reorder search engines with China-friendly options first, mark
  DuckDuckGo/Perplexity/Brave as hard to access in mainland China

- Add Baidu Search row to web search table (after DuckDuckGo)
- zh: reorder table with Baidu/Tavily/GLM first, accessibility notes
