biondizzle cae87fd744 WIP: confirmed row_sum is wrong (5.5 vs correct 29.22 for row 0)
The packed f32x2 reduction SHOULD sum all 128 exp2 P values but gives
a result ~5.3x too small. Need to debug inside the kernel with print
statements to see what values the reduction is actually summing.

Unnormalized P@V is perfect (cosine 0.999998). row_max is correct
(because P is correct). The bug is specifically in row_sum computation.
