Params class abstract
The abstract base class for all input parameter objects passed to a Usecase.
By enforcing a single, typed object as input, the Usecase signature remains stable, improving maintainability and clarity even if the required parameters change.
All concrete parameter classes must be immutable and define validation logic.
