Gino Lu 0f8b58ac88 sparse_attn: R25 Step 1 A1 — per-warp PV-skip (paper Algorithm 1) + V0 instantiation ...

Preserve the R25 Step 1 "A1 / redesign D" state before redesigning toward "B"
(per-CTA PV-skip matching upstream shipped reference). This snapshot lets us
restore A1 if the B redesign fails.

A1 redesign D pipeline (per-warp, arithmetic-only PV-skip, wrapped in
`if constexpr (kEnablePVSkip)`):
  - include/ck_tile/ops/sparse_attn/pipeline/block_fmha_pipeline_qr_ks_vs_async_sparge.hpp
  - include/ck_tile/ops/sparse_attn/kernel/fmha_fwd_sparge_kernel.hpp

V0 instantiation wiring (per gino_tmp/R25/programmer/v0_instance/REPORT.md):
  - example/ck_tile/50_sparse_attn/codegen/ops/fmha_fwd_sparge.py
  - example/ck_tile/50_sparse_attn/fmha_fwd_trek.hpp
  - example/ck_tile/50_sparse_attn/sparge_blockmap_trek.hpp
  - example/ck_tile/50_sparse_attn/sparge_blockmap_inst.cpp
  - example/ck_tile/50_sparse_attn/codegen/cpp_symbol_map.py
  - example/ck_tile/50_sparse_attn/CMakeLists.txt
  - example/ck_tile/01_fmha/CMakeLists.txt
  - example/ck_tile/50_sparse_attn/test_sparge.cpp (-pv_skip_compile=0|1 CLI)

This commit excludes all *_REVIEW.{hpp,cpp} mirror files (left untracked) and
all build artefacts. _vsa.hpp / _jenga.hpp are not modified.
