A Hierarchical Minecraft Agent

A research fork of MineStudio exploring a three-system Minecraft agent: verifier-backed mechanics, STEVE-1 motor control, and higher-level task planning. In a paired 100-episode stone-acquisition screen, one targeted checkpoint reached 66% success versus 37% for the vanilla reference. Later router and PPO attempts regressed, the live full hierarchy remains unvalidated, and the latest iron-pickaxe run completed none. A work in progress with mixed results.
