/**
 * Re-sync the vendored @photo-gallery/sdk from the sibling SDK checkout.
 *
 * The SDK is not published to a registry yet, so it is vendored into `vendor/photo-gallery-sdk`
 * and depended on as `file:./vendor/photo-gallery-sdk` — a path INSIDE this repo, so CI and Vercel
 * (which only ever check out this repo) can resolve it. See vendor/README.md.
 *
 *     npm run sync:gallery-sdk
 *     git add vendor/photo-gallery-sdk && git commit -m "chore: sync @photo-gallery/sdk"
 *
 * Only what the package would publish is copied. Its `node_modules` is deliberately left behind:
 * without it the SDK's sources resolve `@types/react` from this repo (React 19) instead of the
 * pnpm workspace's React 18, which is what lets them type-check here.
