feat(saolei): 交互玩扫雷每一步自动出 PNG

Browse Source 
- play_saolei.tcl: k 每执行一个按键动作就存 shots/NNN_<按键>.png，并覆盖
  shots/latest.png（在 VS Code 里开着 latest.png 即可每步自动刷新）；新增 view 命令
- fb2png.py: 新增 --quiet（只写 PNG 不打印，供脚本批量截图）
- tb_saolei*.v: 仅格式调整（case 分支拆行），无语义变化
实测：k cuuuuc -> shots/001_c.png ... 006_c.png，每张 640x480 正常
