Create a new interactive component for Bulgarian Solitaire. This component will allow users to select a number `n` (2-6), visualize a container with `1+2+...+n` boxes, and arrange these boxes into `1+2+...+n` columns. Users can drag and drop boxes between columns and return them to the container by double-clicking. A "Play" button will initiate the simulation of the Bulgarian Solitaire process until a steady state is reached. This interactive will be added to the Puzzles section.
