blocks_ranking_size

Auto-authored atomic skill for blocks_ranking_size.

Goal: There are three cubes of the same shape but different sizes (a large, a medium, and a small block) scattered at random positions on the table. Perceive and ground each cube, judge their relative sizes, then pick them up one at a time and place them into a neat left-to-right row arranged largest → medium → smallest (the large block at the smaller x on the left, the small block at the larger x on the right, all sharing the same y line). Grasp each block with the arm on its side (left arm if it is on the left, right arm if on the right), lift it clear, and place it at its size-ranked slot with the blocks aligned and evenly spaced, releasing each before moving the next.

Success: The three blocks form one aligned row with x(large) < x(medium) < x(small) and the gripper open.
