D1.5: Implement correction epilog with paired atoms (get_tmem_load_op + get_smem_store_op)
...
One-way: TMEM → registers (normalize) → SMEM → GMEM
Based on CUTLASS FMHA reference's correction_epilog pattern.
Eliminates TMEM round-trip error for O normalization.
O rescale (kt>0) still uses old atoms (separate fix).

D1.5: Revert to pre-epilog backup - correction epilog refactor is complex, will do incrementally
...
The correction epilog (TMEM→reg→SMEM→GMEM one-way trip) is the right approach
but the TMA store from SMEM requires proper partitioning that needs more work.
Reverting to the known-working state (with 3% TMEM round-trip error) to focus
on the SMEM-P write first.

- One-way: TMEM → registers (normalize) → SMEM → GMEM
- Eliminates TMEM round-trip error for O normalization
- O rescale (kt>0) still uses old atoms (fix later)

D1.5: Replace TMEM round-trip normalize with correction epilog (one-way: TMEM→reg→SMEM→GMEM)
...
- Remove noop + normalize TMEM round-trips (3% error per trip)
- Use epilogue_tmem_copy_and_partition for TMEM→reg (paired atoms)
- Use epilogue_smem_copy_and_partition for reg→SMEM (paired atoms)
- Apply 1/row_sum normalization in register space (exact)
- TMA store from SMEM→GMEM (no TMEM write-back)
- Add iter_acc_early_release_in_epilogue attribute
- Update SMEM-P comments to reflect coordinate-indexed fallback
