Cave Utility: Bats drop Guano to create specialized Fertilizer

Bats currently have no gameplay utility in Minecraft. To fix this, bats resting on cave ceilings should occasionally drop Guano over time (similar to how chickens drop eggs). Crafting & Mechanics: * Guano can be combined with Bone Meal or Compost to craft Fertilizer. * Alternatively, Guano can be used on its own as a more potent variant of Bone Meal. Gameplay Benefit: When applied to crops, Fertilizer would immediately skip 2–3 growth stages instead of just one, significantly cutting down the time it takes for crops to fully mature. This gives players a fantastic reason to seek out or even build bat sanctuaries in their survival worlds, turning a purely ambient mob into a highly useful mechanic for farmers.
