Sit and Lay

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): SitandLay did not start: java.lang.NoClassDefFoundError: net/minecraft/world/level/BlockGetter; SitandLayClient did not start: java.lang.NoSuchMethodError: 'com.mojang.blaze3d.platform.InputConstants$Key com.mojang.blaze3d.platform.InputConstants.getKey(java.lang.String)'.
