Migration to LeRobotDataset v3.0

Migrated to LeRobotDataset v3.0 with SO-100/101 joint state/action mapped to the post-#777 physical frame (in degrees).

• Source: HuggingFaceVLA/community_dataset_v3 (Cornito/so101_test3)
• Codebase version: v2.1 -> v3.0
• Original joint encoding: legacy degrees (old community frame, pre-#777 convention)
• Joint values: per-joint offsets and axis directions corrected to the post-#777 frame (values stay in degrees)
• Robot type: so101
• Action dimension: 6
