Merge branch 'main' into feat/robotwin-benchmark

Resolves conflicts introduced by the RoboCasa365 benchmark merge on main
(PR #3375) overlapping with this PR's benchmark CI scaffolding.

- .github/workflows/benchmark_tests.yml: keep both the RoboTwin 2.0 job
  (from this branch) and the new RoboCasa365 job (from main).
- docs/source/_toctree.yml: list both `robotwin` and `robocasa` pages
  under the "Benchmarks" section.
- scripts/ci/extract_task_descriptions.py: keep both
  `_robotwin_descriptions` and `_robocasa_descriptions` helpers and wire
  them into `main()` alongside each other.
