Correct way to bundle dependencies types in generated .d.ts

Hi, My library: https://github.com/meshtastic/js bundles one of it's dependencies as it comes from another package registry, this part is working, however I need the dependencies types to also be bundled.

My library re-exports the dependency as follows:
```ts
export * as Admin from "@buf/meshtastic_protobufs.bufbuild_es/meshtastic/admin_pb.js";
```
The JS code is correctly bundled, but the generated .d.ts file still has an import from the original dependency that is not resolved when using the library:
```ts
import * as config_pb_js from '@buf/meshtastic_protobufs.bufbuild_es/meshtastic/config_pb.js';
```

Reproduce the meshtastic/js setup described in the issue and inspect the generated .d.ts output, especially its import from @buf/meshtastic_protobufs.bufbuild_es. Trace how declaration output handles the re-export, then verify that the dependency types are bundled or resolved for consumers without the original registry dependency.
