P7: Document TMEM column layout, add multi-row softmax test
...
docs/p7_tmem_column_layout.md: Verified that tcgen05.ld 32x32b.x8 is
the correct instruction for multi-row softmax. Each call reads 8 KV
positions for 32 rows. No instruction change needed from single-row.
test_p7_multi_row_softmax.py: Tests T=1,4,32,64,128 at various HD and N.
Gate: cos >= 0.999996.

P5: in-kernel multi-KV-tile FA2 online softmax in fmha_6warp_multihead.cuh
...
- Kernel loops over KV tiles internally with running max/sum rescale
- SMEM accumulator sOacc[hd] replaces TMEM accumulation across tiles
- P is UN-NORMALIZED for multi-tile (exp(s-max), not /sum)
- Per KV tile: QK→softmax→PV→TMEM→read→add to sOacc
- Final: O = sOacc / running_sum
- Single tile (n_kv_tiles=1): same as before, no rescale
- Updated CAPI, Python loader, production.py fast path
- Added multi-tile test cases (N=256, 512)
