add_donut_chart
Create a part-to-whole donut from one category and one nonnegative numeric value. The contract contains only donut-relevant controls. Use style_donut_slice for a later one-slice edit. MODEL GUIDANCE: Use only for one simple part-to-whole with a small number of categories that sum to a meaningful total. Prefer bars when precise ranking matters.
