sync_geometry_to_workers Subroutine

   subroutine sync_geometry_to_workers(sys_geom, comm)
      !! Synchronize geometry coordinates from master rank to all worker ranks
      !! This is needed when master rank updates coordinates for optimization/dynamics
      !!
      !! TODO: Implement explicit broadcast if needed. Currently, the fragmented
      !! calculation infrastructure may already handle geometry distribution.
      !! For unfragmented calculations on master rank only, this is not needed.

      type(comm_t), intent(in) :: comm

      ! NOTE: For now, we rely on the existing calculation infrastructure
      ! to handle geometry as needed. If explicit broadcasting is required,
      ! we can add MPI send/recv logic here later.
