Fix permawebfuel docs specifically for AR.IO

[dpshde]

The permawebfuel documentation integration needs improvements, specifically for AR.IO related content.

Issues:

• AR.IO specific documentation may not be properly indexed or displayed
• Documentation search results need better filtering/relevance
• Potential gaps in AR.IO SDK and gateway documentation

Tasks:

• Audit current permawebfuel docs integration
• Identify missing or improperly indexed AR.IO documentation
• Improve AR.IO specific documentation search and display
• Verify all AR.IO SDK documentation is accessible
• Test documentation search with AR.IO-specific queries
