Cannot import C:\comfyui2025\ComfyUI\custom_nodes\ComfyUI-LTXVideo module for custom nodes: cannot import name 'interleaved_freqs_cis' from 'comfy.ldm.lightricks.model'

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Yesterday everything was working normally with the latest update, today before opening ComfyUI I started the update and upon startup it showed this error resulting in lost nodes due to not loading the extension of the LTX nodes.

### Actual Behavior

Cannot import C:\comfyui2025\ComfyUI\custom_nodes\ComfyUI-LTXVideo module for custom nodes: cannot import name 'interleaved_freqs_cis' from 'comfy.ldm.lightricks.model'

Start with the traceback in custom_nodes/ComfyUI-LTXVideo/embeddings_connector.py and compare its imports with comfy/ldm/lightricks/model.py. Check how custom_nodes/ComfyUI-LTXVideo/__init__.py loads the LTX components, then reproduce the import failure on ComfyUI 0.28.0. Done means the LTXVideo custom node imports successfully and its nodes are available without the reported ImportError.
