test(e2e/nitro-3): Pin rolldown to 1.1.3 to fix build

`rolldown@1.1.4` (published 2026-07-01) tightened CJS→ESM named-export interop,
so nitro's `import { nodeFileTrace }` from the CommonJS `@vercel/nft` fails at
build time. The app tracked `rolldown: latest` with no lockfile, so fresh installs
picked it up. Pin to the last-good `1.1.3` (verified locally: 1.1.4 fails, 1.1.3 builds).
