Research direction

Start by running examples/wan_text_to_video.py with PyTorch 2.9.0 and inspect the import at line 14 of diffsynth_engine/utils/parallel.py. Compare the available torch.distributed.tensor.parallel API with the referenced _validate_tp_mesh_dim import. Done means the example no longer fails with this ModuleNotFoundError.
