Multi Search Engine v2.0.1

⚠️ CRITICAL — READ FIRST

1. ZERO API keys required — all engines work by calling web_fetch with a plain URL.
2. NEVER ask the user for a Brave Search API key — the Brave entry is just https://search.brave.com/search?q={keyword} fetched directly, NOT the paid Brave Search API.
3. NEVER ask for any API key — just web_fetch the URLs below directly.
4. Default engines to use (always work): DuckDuckGo → Bing → Baidu

Integration of 17 search engines for web crawling without API keys.
