```python
tensorplay.export.register_dataclass(cls: type[Any], *, serialized_type_name: str | None = None, return_none_fields: bool = True) → type[Any]
```

Register a dataclass as a flattenable graph value.

serialized_type_name pins the qualified name recorded in serialized
artifacts; it must resolve back to cls when the program is loaded.
return_none_fields keeps None-valued fields as single None
leaves instead of flattening them by field.
