  • fix: handle Transformers v5 BaseModelOutputWithPooling return types

Transformers v5 changed get_text_features, get_image_features, and
get_audio_features to return BaseModelOutputWithPooling instead of
plain tensors. This caused AttributeError when tensor operations
like .norm() were applied directly to the output.

Added isinstance(output, BaseModelOutputWithPooling) checks to
extract pooler_output when needed, maintaining backward compatibility
with Transformers v4 tensor returns.

Affected model wrappers:

  • clap_models.py: text path (audio path already handled)
  • align_models.py: text and image paths
  • wav2clip_model.py: text path (CLIP encoder)
  • llm2clip_models.py: text and image paths
  • siglip_models.py: text and image paths (previously accessed
    .pooler_output directly without fallback)

Closes #4081
