feat(website): add GitHub Pages as fallback deployment (#21)

- Add GitHub Pages deployment to workflow alongside Cloudflare Pages
- Both deploys run automatically on push to main when website/** changes
- Fallback URL: https://devitools.github.io/arandu/
- Add .nojekyll to prevent Jekyll processing
- Document dual-deployment strategy in website/README.md and CLAUDE.md

This provides redundancy if Cloudflare has issues or if corporate networks
block arandu.app domain resolution.

+## 🌐 Access URLs
+
+### Primary (Cloudflare Pages)
+- **URL:** https://arandu.app
+- **CDN:** Cloudflare global network
+- **Deploy:** Automatic via GitHub Actions
+
+### Fallback (GitHub Pages)
+- **URL:** https://devitools.github.io/arandu/
+- **CDN:** GitHub CDN
+- **Deploy:** Automatic via GitHub Actions (same workflow)
+
+## 🚀 Deployment
+
+Both deployments happen automatically on push to `main` when `website/**` changes:
+
+1. **Cloudflare Pages** - Primary deployment
+2. **GitHub Pages** - Fallback deployment (via `gh-pages` branch)
+
+If Cloudflare experiences issues, use the GitHub Pages URL as an alternative.
