Function moveAllRobotsHomeToDefaultOptimized

Optimized setup to move all robots from home to their default board positions.

Behavior:

• Main pieces (default rows j = 2 for white, j = 9 for black) move straight onto the board in parallel.
• Pawns (default rows j = 3 for white, j = 8 for black) first move into the deadzone in parallel, then travel along the deadzone to align with their file, and finally move onto the board to their default squares in parallel.
