Fix the bug and add the claw-swinging function. — Doll Catching Simulator Steam update #305100

- Added a claw-swinging operation. Pressing the claw hook three times in a left-right cycle will make it glow and significantly increase the chance of grabbing. - Added physical collision effects for the claw. - Fixed the bug where dolls would fall out of the claw machine. - Fixed the issue where small dolls would get stuck on the claw. - The claw now pauses for 0.1 seconds at the bottom before grabbing.
