Matrix benchmark

Stable old/materialized-B Pearl path, full requested matrix:

K = 2,3,4,5,6
C = 1,4,8,16,32,64
t ~= 50,180,350,700,1400

Coverage: 30 K/C cells x 5 prompt buckets = 150 rows.

Best mean output throughput across prompt buckets: K=2, C=64, 1039.1 output tok/s.

Notes

The B-on-chip fused Pearl R128 path is not included in these final results. It was rebuilt as R128 128x128x128 stages=2 to fit H100 SMEM but still crashes requests with CUDA illegal instruction; stable results here use the old/materialized-B path.
