Add Next.js source files for GitHub Actions build

- Add package.json and package-lock.json (GitHub Actions needs these)
- Add Next.js config files (next.config.js, tailwind.config.js, tsconfig.json)
- Add src/ directory with all Next.js source code
- Add proper GitHub Actions workflow for Next.js builds
- This fixes the 'Dependencies lock file not found' error

All 14 articles are now in src/app/guides/ and will be built by GitHub Actions
