> Cross-location moves via {{LocationBalancingAlgo}} have zero follower awareness. Fixing this requires:
>  # Passing {{ts_with_followers_by_table_and_tag}} into {{LocationBalancingAlgo::GetNextMove()}} — currently it only receives {{LocationBalancingInfo}}
>  # Applying the same two-candidate (non-leader vs fallback) pattern as {{TwoDimensionalGreedyAlgo}}
