A field guide for discovered mobs

Add a craftable Field Guide that gradually fills with information as players discover different mobs. Each entry could include the mob's natural habitat, food, breeding requirements, taming method when applicable, and drops that the player has observed. Entries should remain undiscovered until the player encounters the relevant mob, so the guide does not reveal information about creatures they have never found. Rare behaviors and hidden mechanics could remain undocumented until the player discovers them. The guide should work entirely in Survival without commands, giving exploration a useful long-term reward and helping players learn the game's creatures naturally.
