Browse source 
* chore: add npm + vite for progressive enhancement

* fix: update Dockerfile to copy only the dist folder contents

* fix: update Dockerfile to use multi-stage build for optimized production image

* fix: correct nginx config file copy command in Dockerfile

* chore: add netlify configuration for build and redirects

* chore: split public and src

* migrating all util files from js to ts

* feat: Implement HeightmapGenerator and Voronoi module

- Added HeightmapGenerator class for generating heightmaps with various tools (Hill, Pit, Range, Trough, Strait, etc.).
- Introduced Voronoi class for creating Voronoi diagrams using Delaunator.
- Updated index.html to include new modules.
- Created index.ts to manage module imports.
- Enhanced arrayUtils and graphUtils with type definitions and improved functionality.
- Added utility functions for generating grids and calculating Voronoi cells.

* chore: add GitHub Actions workflow for deploying to GitHub Pages

* fix: update branch name in GitHub Actions workflow from 'main' to 'master'

* chore: update package.json to specify Node.js engine version and remove unused launch.json

* Initial plan

* Update copilot guidelines to reflect NPM/Vite/TypeScript migration
