This is useful when enabling PnP with `enableGlobalCache: true`, but users must ensure there are no cross-project requires across Yarn PnP projects. |
 
 In the context of `@rspack/resolver`, the `tsconfig.references` option helps isolate the `paths` configurations of different TypeScript projects.
 This ensures that path aliases defined in one TypeScript project do not unintentionally affect the resolving behavior of another.
