feat(website): migrate deployment from GitHub Pages to Vercel (#394)

* fix(website): enable Next.js static export for GitHub Pages deployment

- Add output: 'export' and images.unoptimized for static site generation
- Update workflow artifact path from dist to out (Next.js export output dir)
- Restore CNAME file to preserve gosqlx.dev custom domain on deploy

* feat(website): migrate deployment from GitHub Pages to Vercel

- Build WASM in CI (requires Go), then deploy prebuilt output to Vercel
- Vercel project: gosqlx-website (prj_dC5W1JVnUjCEZ25UQS4XqyXKSwPV)
- Custom domain gosqlx.dev configured on Vercel project
- Drop pages/id-token permissions, no longer needed

* fix(website): remove output: export — not needed for Vercel deployment

Static export was added for GitHub Pages but breaks Vercel features
(headers, redirects, sitemap route). Vercel handles SSR natively.
