Add GitHub Pages deployment with static website

[Copilot]

This PR adds a complete GitHub Pages deployment setup for the voxel-render project, including a beautiful static website and automated CI/CD workflow.

Changes Made

🚀 GitHub Actions Workflow

Added .github/workflows/pages.yml that automatically deploys the website to GitHub Pages on every push to the main branch. The workflow:

• Uses official GitHub Pages actions with proper permissions
• Supports manual workflow dispatch for on-demand deployments
• Handles concurrent deployments safely
• Deploys the entire repository as static content

🎨 Static Website

Created a professional index.html homepage featuring:

• Modern responsive design with purple gradient background
• Clean typography and intuitive layout
• Four feature sections highlighting voxel rendering capabilities:
  • High Performance rendering algorithms
  • Flexible rendering techniques
  • Easy integration with existing pipelines
  • Scalable architecture for large datasets
• Mobile-friendly responsive grid layout
• Direct integration with the GitHub repository

📚 Enhanced Documentation

Updated README.md to include:

• Comprehensive project description
• Feature overview with icons
• Link to the deployed GitHub Pages site
• Professional formatting and structure

Deployment

Once merged to main, the website will be automatically deployed and available at:
https://lucasgenoud.github.io/voxel-render/

The implementation follows GitHub Pages best practices and provides a professional web presence for the voxel-render project.
