feat: implement build system and development workflow

- Add npm scripts for CSS/JS compilation (build:css, build:js, build)
- Create PowerShell build automation script
- Document development workflow in README
- Add troubleshooting guide for build issues
- Specify proper file structure and compilation process

Supports Tailwind CSS v3.4.0 and esbuild bundling with source maps.
