Improve Npcs For Map Making

Body: Hello Mojang team, I would like to suggest improvements focused only on NPCs, to make them more useful for professional map making with command blocks (without mods). Optional health/heart bar for NPCs. More creative NPC skins (warriors, monsters, villagers, adventurers, etc.). A dialogue system with multiple messages and choices, instead of only one message. Simple behaviors for NPCs, like following, protecting, giving quests, or fighting. These features would greatly help map creators build more immersive and professional maps in Bedrock and Education editions. Thank you for considering this idea!
