PiPER black-box task

Task: Pick up the black box and place it in the basin.

Two views: overhead image and wrist_image, 20 FPS, 256x256 RGB videos. State: raw feedback, six joint angles in radians and gripper width in meters. Actions: next-frame feedback clipped to deployed command limits, not measured commands. See drag_action_labels.json and conversion_validation.json for provenance and checks.
