ComfyUI Drag Error Fix

Suppresses the "Cannot read properties of undefined (reading 'config')" error
that occurs when dragging nodes with widgets from the sidebar.

This is a ComfyUI frontend bug that affects all nodes with widgets.
This extension provides a global fix without modifying ComfyUI core.

class DragErrorFixNode:
    """
    A minimal utility node that loads the drag error suppression.

    The actual fix is in the web extension (web/fix.js).
    This node just provides a visible indicator that the fix is installed.
