feat: enhance button design system with improved UX and visual hierarchy

- Redesign primary buttons with solid green styling for clear call-to-action
- Update GPS button to professional outline style (secondary priority)
- Implement consistent hover effects with translateY animations
- Add improved button variants with better color contrast
- Update README.md to reflect current v3.0.0 features and tech stack
- Add comprehensive API reference documentation
- Update .gitignore to exclude internal documentation files

UI/UX improvements:
- Primary actions now have clear visual prominence
- Secondary actions use subtle outline styling
- Enhanced accessibility with better color contrast
- Consistent interaction feedback across all buttons
- Professional design suitable for research environments
