Add GitHub Pages deployment

- Static export via next.config.ts (output: export)
- PAGES_BASE_PATH env var for base path (/docs-hunting for GitHub Pages, empty for custom domain)
- GitHub Actions workflow: build on push to main → deploy to Pages
- images.unoptimized: true for static export compatibility
