Performance & Caching

• Fetched Block Entity (BE) textures from item cache and implemented caching for loottable profile textures to accelerate plushie loading and placement.

• Implemented rendering guards on shapes/skins and prevented rendering without an owner to minimize visual pop-in.
• Added block particle effects on placement/breaking.
