    tools: Add osk-preview.sh utility script
    
    This script launches a nested GNOME Shell with the osk-preview mode,
    loading the file specified through arguments.
    
    Optionally, --vertical/--horizontal can be passed to have the nested
    shell instance represent the specified layout with a common resolution.
