Free Minecraft Models

FreeMinecraftModels 2.10.1:

• Fixed a duplicate persistent prop cleanup issue where multiple armor stands for the same model could accumulate on the same block.
• Added startup/chunk-load cleanup that keeps one prop per model per block and logs how many duplicates were removed.
• Removed the temporary props.yml registry path; props are tracked through their armor stand backing entities again.
• Tightened custom model item placement so off-hand interactions do not double-place models.
