support HotReload on code changes

### Feature Idea I tried to use https://github.com/kijai/ComfyUI-HotReloadHack ( @Kijai 's auto reload of comfy if files change) but hiddenswitch comfyui lacks nodes.py so the line: ``` from nodes import load_custom_node ``` fails. Would be nice to either make this work, or replicate the functionality of it. ### Existing Solutions _No response_ ### Other _No response_
