feat(看板娘): 换成一整套全身立绘，说什么话摆什么表情；闲着会做自己的事、久了打盹，还能藏到屏幕边上只探个头

立绘换成 Sutera-Diffusus/dsh-whale-musume 的 92 张（MIT，许可原文放在图旁边），全部用上：
- 每组台词配一两张：做对了笑、做错了垮脸、编译错误慌、炸毛、背过身冒黑气、被摸完头脸红冒爱心……
- 被拎着上半身拖和揪着尾巴拖是两张；一直连着摸会被摸得笑出来。
- 5 分钟没人碰换一张日常（做饭、钓鱼、画画、听歌……，冬天下雪、春夏打伞，晚上穿睡衣），
  20 分钟睡着，点她先被吵醒说一句。比赛页不换。
- 往屏幕外拖过一截再松手，就缩进下、左、右那条边只探个头，往外一拖又出来。
- 节日当天换节日装（春节、中秋、圣诞、万圣、情人节）。
只有平时那张跟页面一起下，别的用到才下、下好再换，不闪白。
