[Bug]: middleware chunk name collision when using nodejs middleware runtime in NextJS with @segment/analytics-next ^1.77.0

[igordonin]

Summary

When using NextJS 15.5.12 and configuring middleware.ts to use NodeJS runtime instead of Edge, there's a chunk name collision with middleware

How to reproduce

Configure any minimal middleware in middleware.ts and add @segment/analytics-next:1.77.0 or above to the dependencies.

export const config = {
  matcher: ...
  runtime: 'nodejs',
};

Error when building the application:

Failed to compile.
../node_modules/.pnpm/@segment+analytics-next@1.81.1_encoding@0.1.13/node_modules/@segment/analytics-next/dist/pkg/core/analytics/index.js
It's not allowed to load an initial chunk on demand. The chunk name "middleware" is already used by an entrypoint.
