docs: comprehensive documentation polish & CI/CD automation

Major Updates:
- Rewrote all docs in beginner-friendly 'ELI5' language
- Created docs index with user journey navigation
- Added complete getting-started guide for novice users
- Set up GitHub Container Registry (GHCR) automation
- Configured GitHub Pages deployment for documentation

Documentation:
- docs/index.md - Central navigation hub
- docs/getting-started.md - Step-by-step beginner guide
- docs/github-setup.md - CI/CD setup instructions
- README.md - Complete rewrite in accessible language
- CONTRIBUTING.md - Contributor guidelines
- Multiple comprehensive API and schema docs

CI/CD Workflows:
- .github/workflows/docker-build.yml - Multi-platform builds to GHCR
- .github/workflows/docs.yml - Automated docs deployment to Pages
- Supports main (latest), development (dev), and version tags
- Automated testing of built images
- Beautiful documentation site with dark theme

Benefits:
- Zero barrier to entry for new users
- Automated Docker builds (AMD64 + ARM64)
- Professional documentation site
- No Docker Hub account needed (uses GHCR)
- Complete CI/CD pipeline

All 7 implementation phases complete - project is production ready!
