Refresh README: link GitHub repo; add L20 directional-hub / RAW=Turbo / refiner-diffuse / rebalance-lever findings; clarify solo probes are diagnostic (attention-mixed slot, not a clean layer)

Use Krea's terminology (select_layers / selected hidden-state layers); note ComfyUI 'tap' alias

Add Krea 2 projector interpretability artifacts (original weights + 12 per-tap probes)
