Chopper, Miner, and Builder villager

This idea adds a cooperative village supply chain using existing blocks and one new workstation so villages feel alive without feeling modded. None of these villagers spawn naturally; players activate them by placing their job sites.

The Three Roles:

- Chopper (Sawmill): The Sawmill acts like a wooden Stonecutter for crafting stairs, slabs, and fences. Choppers cut nearby trees, replant saplings only near the village and Sawmill, and share logs and planks with Miners and Builders. They trade biome-specific saplings, logs, sticks, and tree loot.

- Miner (Furnace): Miners dig 3x3 tunnels, place torches, and store blocks in nearby chests. Using planks shared by Choppers, they build wooden bridges and supports across caves so they do not fall. They defend themselves with a shield, smelt ores, and trade gems, minerals, stone, and pickaxes.

- Builder (Crafting Table): Builders construct new houses one block at a time in 8x8x8 empty spaces next to player-made paths using shared wood and stone. They buy building blocks like planks, cobblestone, logs, and terracotta for emeralds.

This creates a natural, player-triggered village economy that expands slowly and safely!
