Added a feature.

● Added a pause function. During pause, both CPU and GPU usage are significantly reduced. However, it is not recommended to pause for extremely long periods, as data stored in memory may be unexpectedly released by third-party programs, potentially causing issues in the game.

● Fixed incorrect Japanese descriptions for certain items.

● Fixed a bug where wooden weapons gave scrap metal when disassembled.

● Increased the horizontal support distance of buildings to reduce the chance of unexpected collapses.
