khyari hamza 229dbc8925 refactor(decision): address PR review feedback
- add with_superseded_by() helper for frozen model mutation
- document frozen model + superseded_by interaction in docstring
- clarify sequence_number uniqueness is a persistence concern
- add scenario for invalid corrects_decision_id ULID validation
- add scenario for with_superseded_by copy behavior
- type step helper dict as dict[str, Any]
