chore(web): wire vercel deploy — static export, tracked generated JSONs

vercel.json runs `next build` directly (skipping pnpm content) so deploys
work from a clean clone where the gitignored eval data is absent. The
generated JSONs are now tracked and the content script preserves them
when sources are missing instead of clobbering with empty fallbacks.
Pinned pnpm + node engines for reproducible Vercel builds.
