…in serialization ### Summary Objects that implement `__getattr__` (like `rdflib.Namespace`) caused serialization errors because `hasattr()` returns `True` for any attribute name, but the returned value may not be callable. Added `getcallable()` utility function that safely retrieves callable attributes, returning `None` if the attribute doesn't exist or isn't callable Closes #8096
