- [nitpick] The require() polyfill was removed from the injected entry file; if user code still relies on
require, it could break. Verify that all dependencies use ESM imports or reintroduce a lightweight polyfill.

The import OnResolveArgs is no longer used in this file; consider removing it to clean up unused code.

[nitpick] Use console.error instead of console.log when logging errors, so they are correctly classified in stderr.
Suggested change

The options field is assigned in the constructor but never referenced elsewhere; consider removing it or using it to drive configuration.

[nitpick] This JSON skip regex is duplicated in CommonDirectiveTransformer; consider extracting it into a shared constant to reduce duplication.
