`meta/info.json` names the 8-value state `['state']` and the 7-value action `['actions']`. This commit names each component, as LeRobot's LIBERO environment builds them: the end-effector position, its axis-angle orientation, and the two gripper finger joints for the state; robosuite's OSC_POSE delta and the gripper command for the action. Only `meta/info.json` changes.
