refactor: convert InputPackage from tuple to named struct

- Replace tuple-based InputPackage with named struct for better type safety
- Add proper field names and documentation
- Fix typo in InputRelativePathBuf type name
- Update add_input and remove_input methods to work with new struct
- Maintain serialization compatibility with derive attributes
