websites to provide structured information for Large Language Models (LLMs).

Features:

• Configurable content per website through website settings
• Multi-website support
• Default content generation when not configured
• Proper HTTP headers (text/plain, cache control)

The content can be configured in Website > Configuration > Settings,
under the "Website Info" section.
