Validates visual feature consistency between a policy config and provided dataset/environment features.
Validation passes if EITHER:
- Policy's expected visuals are a subset of dataset (policy uses some cameras, dataset has more)
- Dataset's provided visuals are a subset of policy (policy declares extras for flexibility)
Args:
cfg (PreTrainedConfig): The model or policy configuration containing input_features and type.
