refactor: enhance type definitions for package handling

- Introduced `NormalizedPackageJson` and `NormalizedReadResult` interfaces to improve type safety and clarity in package handling.
- Updated the `readPackageUpSync` function to utilize the new type definitions, ensuring consistent and accurate package data retrieval.
