WHY IT NEEDS A POLICY

Why push_set_button_led needs a policy

This tool modifies the hardware state of an Ableton Push controller by setting LED colors and modes. It creates/modifies a visual state on the hardware device. While it's reversible (LEDs can be changed again), it does affect external hardware state. It doesn't execute code, delete data, or involve finances — it's a Write operation targeting hardware feedback state.

From the tool's definition Set the LED color and mode for a Push transport or utility button... returns sent=true with the accepted button/color/mode
