Optimize storage usage to fix 50GB limit exceeded error

- Update README.md to request 'large' storage instead of 'medium'
- Optimize download_models.sh to use streaming/hub access for large models
- Move HF cache to /tmp to use temporary storage
- Only download essential wav2vec2 model locally
- Create config placeholders for large models to use HF Hub streaming
- This should keep storage usage under 50GB limit
