// Actually, if we have the *mesh* path, we can try to use that if the C++ handler supports it,
// OR we might need to inspect the mesh asset to find its skeleton.
// For now, let's settle for: if user provided meshPath but not skeletonPath, we might need a way to look it up.
// But here we only have actorName.
// Let's defer this complexity unless required.
// Correction: The walkthrough issue said "Skeleton missing".
// Let's assume user MUST provide it or we fail.
// But if we can help, we should.
// If we have meshPath, we can pass it as 'meshPath' and let C++ handle finding the skeleton?
// The C++ 'create_animation_blueprint' handler expects 'skeletonPath'.
// So we'd need to modify C++ to check meshPath->Skeleton.
// Since I'm editing TS only right now, I'll allow passing 'meshPath' in payload if skeletonPath is missing,
// and hope C++ was updated or I should update C++ later.
// Actually, checking args, if 'meshPath' is passed, we should pass it along.
