Feature Request: Custom Menu

This is about:
The function is to modify the right-click custom menu through json, and at the same time provide a button to hide the original plug-in menu
Or control the original menu and submenu ordering

**Recommended Reasons**
Because there are too many existing plugins, and there are many plugins that contain duplicate functional plugins, some of them need to be hidden, and each plugin has different functions, but for the parent menu, I think the categories are customized by the author. Naming, there is no good classification of the plugin
It's like a supermarket has a dozen shelves with different products on them, but each shelf has the same product, and the shelves are not placed in the correct classification area.

The issue requests a JSON-configurable right-click menu system to hide or reorder plugin menus in ComfyUI. Start by examining the UI component that renders the right-click menu, likely in a frontend directory. Look for existing menu definitions and plugin integration points. Determine how plugins register their menu items and how a JSON configuration could override that. 'Done' means a user can provide a JSON file to customize the menu layout and visibility.
