feat: implement zero-configuration auto-enhancement demo workflow

- Add intelligent auto-enhancement that detects viable content elements
- Replace manual enhancement with automated container-first detection
- Support inline formatting (strong, em, span, links) within editable content
- Streamline demo workflow: just demo shows options, auto-enhances on demand
- Clean up legacy commands and simplify directory structure
- Auto-enhancement goes directly from source to demo-ready (no intermediate dirs)
- Add Dan Eden portfolio and simple test sites for real-world validation
- Auto-enhanced 40 elements in Dan Eden portfolio, 5 in simple site
- Achieve true zero-configuration CMS experience
