feat: set up basic project structure and initial styling

This commit initializes the project with a basic Next.js setup, including:
- Integration of `tailwindcss` and `tw-animate-css` for styling.
- Definition of a comprehensive color palette using CSS variables for both light and dark themes, supporting a theming system.
- Implementation of a custom `aurora` keyframe animation.
- Configuration of global CSS styles for `border` and `body` elements.
- Setup of `next.config.ts` with image optimization, performance enhancements, and security headers (X-Frame-Options, X-Content-Type-Options, Referrer-Policy).
- Update of `package.json` to include new dependencies for UI components (`class-variance-authority`, `clsx`, `lucide-react`, `motion`, `tailwind-merge`, `tailwindcss-animate`) and development tools (`@biomejs/biome`, `@tailwindcss/postcss`, `tw-animate-css`).
- Refinement of `app/layout.tsx` to include comprehensive metadata for SEO (title, description, keywords, authors, Open Graph, Twitter cards, robots), preconnect/dns-prefetch links for external resources, favicon, manifest, and mobile app meta tags.
- Restructuring of `app/page.tsx` to use dynamic imports for various sections (Hero, About, Skills, Experience, Projects, Contact, WorkModalities) to improve performance, and integration of `Squares` component for background effects.

This foundational commit prepares the application for further development by establishing a robust and performant base.
