cannot import name '_C' from partially initialized module 'comfy_kitchen.backends.cuda

Found comfy_kitchen backend cuda: {'available': False, 'disabled': False, 'unavailable_reason': "cannot import name '_C' from partially initialized module 'comfy_kitchen.backends.cuda' (most likely due to a circular import) (E:\\AI\\ComfyUI_Mie_V7.0\\python_embeded\\Lib\\site-packages\\comfy_kitchen\\backends\\cuda\\__init__.py)", 'capabilities': []}

Start by reproducing the import failure in the reported embedded Python environment and inspect comfy_kitchen/backends/cuda/__init__.py, which appears in the error. Trace why importing _C leaves the module partially initialized. Done means the CUDA backend imports successfully and its capability report no longer marks it unavailable.
