feat: Implement comprehensive repository improvements

- Set up ESLint and Prettier for code quality
- Split large script.js into modular architecture (DOM, animations, effects, easter-eggs, sound, interactions)
- Organize assets into proper directory structure (assets/css, assets/js/modules, assets/images)
- Add semantic HTML5 landmarks (header, main, nav, footer)
- Implement ARIA labels and keyboard navigation for accessibility
- Set up Vite build system with minification and optimization
- Add CSS custom properties for design tokens
- Create sitemap.xml and robots.txt for SEO
- Add MIT LICENSE
- Expand README with comprehensive documentation
- Set up GitHub Actions CI/CD workflow
- Optimize build output: ~59KB total (30KB image + 13KB CSS + 16KB JS gzipped)
