ClothDojo generated RGB fold

3856 original training episodes, LeRobot v2.1. Dataset records, videos and metadata are preserved byte for byte. RGB videos are training observations, not geometric evaluation inputs. Successful terminal-state selection and evaluation initial-state validation are different checks. This release repairs evaluation initial states only; it does not replace or certify all training initial states against that benchmark gate.
