[MIRROR] mothroaches in the wardrobe (#28266)

* mothroaches in the wardrobe (#83695)

## About The Pull Request
there is a very small chance vendrobes will have mothroaches inside.
this will become apparent as the clothes you buy will come out slightly
damaged and eaten. hitting the vendrobe with a weapon (or throwing the
weapon at it) will cause the mothroaches to come out and scatter
everywhere. mothroaches will now also seek out clothes to eat them

## Why It's Good For The Game
gives more character and depth to mothroach AI

## Changelog
🆑
add: vendrobes may have mothroaches inside them
add: mothroaches will now seek out clothes to eat them
/🆑

* mothroaches in the wardrobe
