chore(build): raise node heap to 8GB for next build type-check

Next.js's type-check worker OOMs at the default 4GB heap on Node 23 for
this project's type graph size. Bumps the heap to 8GB only for the
`next build` invocation inside `bun run build`.

Docker builds are unaffected — `next.config.ts` sets
`typescript.ignoreBuildErrors: true` when DOCKER_BUILD=1, which skips
the type-check pass entirely. This only fixes local `bun run build`.

No functional code changes.
