aloha_transfer_cube_uni3 — ALOHA transfer-cube human demos, uni3 frame selection

Derived from lerobot/aloha_sim_transfer_cube_human (50 human teleop episodes, 50 Hz, 14-D, top cam 480×640). Frame selection: every 3rd frame — 6,700 frames (33.5 %), the ISR paper's baseline. Re-stamped on a uniform 50 fps grid, state/action in degrees (convert rad↔deg at deployment), LeRobot v3.0, task string "Pick up the cube with the right arm and transfer it to the left arm.".

Part of the ISR closed-loop study: results, code, checkpoints and the other arms in Kavin60606/isr-aloha-transfer-cube-experiment. Kept-frame indices per episode: keeps/aloha_transfer_cube_uni3/ep*.npy there.
