2025-11-01: Add Comprehensive Table of Contents to Documentation

[john-mutuma]

What does this PR do?

This PR adds comprehensive Table of Contents (TOC) navigation to all major documentation files, improving discoverability and user experience. This builds on the documentation restructuring completed in PR #66 by adding the final navigation layer.

• Added comprehensive Table of Contents to README.md with 34 sections covering all major content areas
• Completed TOC in doc/FAQ.md by adding missing "Still Have Questions?" section
• Completed TOC in doc/TROUBLESHOOTING.md by adding missing "Additional Documentation" section
• Completed TOC in doc/CONTRIBUTING.md by adding missing "Questions?" and "Recognition" sections
• Completed TOC in doc/ARCHITECTURE.md by adding missing "Additional Resources" section
• Updated AGENTS.md with project history entry documenting the TOC enhancement

Why is it needed?

Problems Solved:

1. README had 41+ sections but no Table of Contents: Users had to scroll through lengthy document to find relevant sections
2. Incomplete TOCs in specialized docs: FAQ, TROUBLESHOOTING, CONTRIBUTING, and ARCHITECTURE were missing TOC entries for some sections
3. Poor discoverability: Full content overview was not visible upfront
4. Not following best practices: Professional documentation should have comprehensive navigation aids

Benefits:

• Improved navigation: Users can jump to any section in 1 click with GitHub anchor links
• Better discoverability: Full content overview visible upfront
• Professional appearance: Follows documentation best practices
• Enhanced accessibility: Screen readers benefit from structured navigation
• Better SEO: GitHub search indexes TOC links
• Time savings: Reduces scrolling time for users seeking specific information

How have the changes been tested?

• ✅ Verified all TOC links use correct GitHub anchor format
• ✅ Clicked through all TOC links to confirm they navigate to correct sections
• ✅ Validated TOC completeness by comparing against actual document sections
• ✅ Confirmed consistent formatting across all documentation TOCs
• ✅ Tested navigation flow in GitHub markdown renderer
• ✅ Verified proper emoji handling in anchor links
