🧬 Add live code evolution display

- Side-by-side comparison of original vs evolved code
- Syntax highlighting with color-coded display
- Real-time tracking of improvements applied
- Shows actual parameter changes (max_depth, criterion, etc.)
- Educational value - see exactly what AI is changing
- Progressive improvements shown generation by generation
