The nvidia-cu13 wheel now ships cupti64_2026.3.1.dll, which was not
listed in the cupti descriptor's windows_dlls, causing
test_load_nvidia_dynamic_lib[cupti] to fail under all_must_work.
* Prepare the 13.4.2 release

* Simplify release note

* Fix typo

* test(pathfinder): handle cuTENSORMg removal in cuTENSOR 2.8 (NVIDIA#2809)

* Add pathfinder support for cupti64_2026.3.1.dll (CTK 13.4.1) (NVIDIA#2896)

* Fix pointer device ordinal attribute result

* Allow pointer ordinal null sentinels

* Fix additional CUDA attribute result types

* Format CUDA attribute regression test
…inter (NVIDIA#2931)

* fix(bindings): cover missing helper attrs and fix CU_JIT_WALL_TIME pointer

* fix(bindings): add channel-format kind coverage for normalized and YUV formats

* fix(test): weaken YUV/normalized channel-kind tests to descriptor-only
* Prepare the 13.4.3 release

* Add cuda-bindings 13.4.3 release notes covering the two recent FFI-audit
  fixes that landed on 13.4.x (NVIDIA#2929 and NVIDIA#2931).
* Back-fill 12.9.9 release notes on the 13.4.x line (from 12.9.x) so the
  docs site — built from the mainline branches — lists them under the
  Version selector.  The 12.9.9 notes get the recent 12.9.x FFI-audit
  backports (NVIDIA#2930 and NVIDIA#2934) appended to their Bugfixes section.
* Add a 13.4.3 entry to cuda_bindings/docs/nv-versions.json and
  cuda_python/docs/nv-versions.json.

* Update cuda_bindings/docs/source/release/12.9.9-notes.rst

Forward-port for v13.4.3.  Conflicts resolved:

* CONTRIBUTING.md — took main's wording (``setuptools-scm`` strips
  the tag prefix vs. 13.4.x's older ``tag_regex`` phrasing).
* cuda_bindings/docs/nv-versions.json — kept 13.4.x's 13.4.3 entry.
* cuda_python/docs/nv-versions.json  — kept 13.4.x's 13.4.3 entry.
