feat: harden Docusaurus docs-site for GitHub Pages deployment

- Add .nvmrc with Node 20 LTS enforcement
- Update package.json engines and add required scripts (clean, check:links, serve)
- Add rimraf devDependency for cross-platform cleanup
- Fix docusaurus.config.js: enable strict link checking (onBrokenLinks: throw)
- Convert to CommonJS module system (module.exports)
- Add sitemap plugin configuration
- Update GitHub Actions workflow for proper docs-site deployment
- Add .markdownlint.json for quality gates
- Set correct edit URLs to develop branch
- Enable trailingSlash: false for GitHub Pages compatibility

All acceptance criteria met for production-ready GitHub Pages deployment
