Ref: https://www.electronjs.org/docs/latest/api/protocol

Proposed Solution

1. learn how to add protocol to system by https://www.electronjs.org/docs/latest/api/protocol
2. Register the comfy:// to system, (also remove the protocol when uninstall)
3. When ComfyUI launch, parse the URI args startsWith "comfy://"
4. When comfy://install-custom-node/:nodeId is called, call comfyui-manager module to install the customNode by :nodeId param
5. When comfy://import/:nodeId is called, call comfyui-manager module to install the customNode by :nodeId param

Potential workflow
