Simple Copper Pipes

Calls something that is not on Kiln's roadmap yet. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): SimpleCopperPipesFabric did not start: java.lang.NoSuchMethodError: 'java.util.Optional net.fabricmc.loader.api.FabricLoader.getModContainer(java.lang.String)'.
