biondizzle 84cd636ba9 Stage C fixes: pv_done_bar sync, acc_scale with scale, fastmath=True ...

- Add pv_done_bar (barrier_id=4): MMA signals PV complete, epilogue
  waits before O rescale (C6) and final normalization (C9)
- Fix acc_scale: exp2(scale * (old_max - new_max)) includes the
  scale_softmax_log2 factor matching CUTLASS FMHA reference
- fastmath=True for both exp2 calls (P computation + rescale)
- No *0.5 (our scalar row_sum pattern initializes (0,0) not (sum,sum))
