Task-string changes only; no data, video, segment or subtask_index changes.

Each now has step subtasks with skill labels and the task fields of fully annotated episodes of the same task, with step intervals aligned by joint motion and fingertip contact. The per-hand descriptions are kept with label hand_actions.
- 11 of those episodes visibly fail (checked on video). They keep only the steps that happen, and an `error` segment with a short note covers the failure frames.
- play_tic_tac_toe (521) and sweep_waste_into_dustpan/season_POC22054_2026_05_30_11_16_03_train episode 0: frame-level subtask_index now follows their step subtasks.
