 * Calculate the final maze score based on performance metrics

 * Final Score = min(1000, max(0, round(Base Score × Size Multiplier)))
 * 
 * Penalties:
 * - Time Penalty = seconds / 10
 * - Keystroke Penalty = keystrokes / 2
 * 
 * @param scoreManager - Current score metrics
 * @param mazeSize - Total cells in maze (rows * cols)
 * @returns Final score between 0-1000
