[Good First Issue] Add real-world before/after examples to docs

[mverab]

The documentation would benefit from real-world before/after examples showing E-GEO optimizations.

What's needed:

1. Find 2-3 public pages to use as examples
2. Run /geo:audit to save before state
3. Run /geo to generate optimized versions
4. Add to docs/examples.md with:
   • Original content
   • GEO score before/after
   • What changed
   • Screenshot of output

Resources:

• Current examples folder: examples/
• Documentation structure in docs/
