cocotb_benches.dau_wide_field_sum_aggregation_tb

Wide-lane field-sum terminal: SLOTS whole quad rows per beat, one beat per cycle, golden-equal to field_sum_rows. The all-ones 128-bit PAD row (ragged tails, upstream drop-by-pad) is neither summed nor counted; the record/close-out protocol is byte-identical to the 64-bit tile. The width-agnostic collect/status harness is shared with the 64-bit bench.
