Touhou Little Maid：BetterGap

1. Added duplicate protection for maid item transport: Each container is now moved only once per round. If duplicate bindings appear on the Gap (the same chest bound twice), they will be automatically merged into one: the terminal UI will show only one entry, and maids will transport it only once. Large chests bound separately on their left and right halves will also be treated as the same container, so items are no longer transported twice.

1.女仆搬运加了重复保护：同一个容器每轮只搬运一次。如果隙间上出现重复绑定（同一个箱子绑了两条），会自动合并成一条：终端界面只显示一个，女仆也只搬运一遍；大箱子左右两半各绑一次的，也会当成同一个容器处理，不再各搬运一份。
