.SYNOPSIS
    Disables AI Actions in File Explorer context menu.

.DESCRIPTION
    Applies HideAIActionsMenu = 1 policy.
    
    File Explorer AI Actions provides AI-powered features in the right-click menu:
    - Image editing with AI (background removal, effects)
    - Text summarization
    - AI-powered file actions
    
    Disabling removes the "AI Actions" entry from the File Explorer context menu.
