Fetches a URL and converts its content to clean markdown for LLM consumption. A pluggable backend chain: pure Ruby httpx + Nokogiri + reverse_markdown by default, a Jina Reader fallback for JS-rendered or blocked pages, and a real-Chrome fallback (Ferrum) that renders JavaScript and lets auto-solving Cloudflare challenges complete. The capability layer only — tool framing (MCP servers, agent tools) is provided by the consumers.
