Bug: `RoboticArm` and `AgenticNavigation` sub-task labels are swapped (L4 / Goal-DrivenExecution)

Hi, thanks for open-sourcing this project — the benchmark design and task taxonomy are genuinely well organized, and the released resources are very helpful for the community. I really appreciate the effort your team put into building and maintaining this benchmark.

I noticed a possible labeling issue in the L4 / Goal-DrivenExecution tasks: it seems that the `RoboticArm` and `AgenticNavigation` sub-task labels may have been swapped. The current mappings appear inconsistent with the corresponding task contents and descriptions. It might be worth double-checking the annotations for these two categories.

| `spatree2` label | session_id | `metricfunc` | question text | actual task |
|---|---|---|---|---|
| `AgenticNavigation` | 5618–5867 (250) | `manipulateeval` | "…translation and rotation for the **robot arm's end-effector**… decompose the **end-effector movement** into 7 steps" | **robotic arm** |
| `RoboticArm` | 5868–6117 (250) | `agenticnaveval` | "**Task: Visual Navigation Action Sequence Generation** … expert **visual navigation agent** … **navigate a robot** …" | **navigation** |

Thanks again for releasing such a valuable benchmark and for your contributions to the community.

Esamina le mappature L4 / Goal-DrivenExecution per gli session_ids 5618–6117, incluse le etichette spatree2 e i valori di metricfunc mostrati nel report. Confronta ogni mappatura con il testo della relativa attività, verifica se le due etichette delle sotto-attività sono scambiate e aggiorna le annotazioni se ciò viene confermato; quindi ricontrolla entrambi gli intervalli di 250 sessioni.
