a22014d21f 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

cb9ebf33fa D5a: Add normalize flag + LSE output
- normalize=True (default): O = softmax(P) @ V (existing behavior)
- normalize=False: O = P @ V (un-normalized) + lse = log(row_sum) + row_max
- LSE tensor passed as optional parameter
- Test includes D5a normalize=False verification with LSE comparison
- Cleaned up SMEM-P debug prints and broken make_tiled_copy_C code
- hd=64 TMEM-P regression: cos 0.973 PASS

9d8f4b8a05 D1: paired atoms epilogue (no TMEM round-trip)
Replace NO-OP round-trip + normalize + epilogue_tma_store with:
- get_tmem_load_op + get_smem_store_op paired atoms
- One-way TMEM→reg (normalize) →SMEM→GMEM
- Eliminates ~3% error from TMEM layout mismatch
- O rescale disabled (single KV tile only for now)
- Pre-computed TMA partitions outside if blocks
