          - Keep the Tavall Studios utility aggregate aligned with authoritative direct Java utility repositories.

          Changes:
          - Advance changed direct Java utility submodule pointers to their canonical main revisions.
          - Initialize nested descendants at revisions pinned by their owning aggregate.

          Validation:
          - Git submodule update completed successfully for every configured direct utility."
