Unable to externalize a dependency

```ts
import { defineConfig } from 'tsup';

export default defineConfig({
clean: true,
entry: ['src/bin/worker.ts', 'src/bin/scheduler.ts'],
external: ['jsdom', 're2', '@contra/temporal-workflows/workflows'],
noExternal: [/^@contra\/(?!temporal-workflows$).*$/u],
sourcemap: true,
splitting: false,
});
```

```
WARN ▲ [WARNING] "@contra/temporal-workflows/workflows" should be marked as external for use with "require.resolve" [require-resolve-not-external] 21:42:10

src/bin/worker.ts:132:35:
132 │ ...owsPath: require.resolve('@contra/temporal-workflows/workflows'),
╵ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

Start with the tsup configuration shown in the issue and the require.resolve call at src/bin/worker.ts:132. Reproduce the warning with the listed entry points and external/noExternal settings, then determine whether the dependency can be externalized without breaking that resolution. Done means the warning is addressed and the worker still resolves the dependency correctly.
