Cherry-pick NVIDIA#2896 (7c4691b, cupti64_2026.3.1.dll) and NVIDIA#2982 (48f55a3, cusparseLt_13.dll). Current CUPTI and cuSPARSELt wheels ship these names, and the Windows pathfinder all_must_work tests fail without them. 13.4.x carries the same fixes.

* Prepare cuda.core v1.2.2 with Python 3.15 support Add Python 3.15 wheels, including the free-threaded build, and keep Python 3.10. #3080 on main adds 3.15 and also drops 3.10, so this commit takes only its 3.15 parts plus the matching 13.4.4 changes. - Cherry-pick #2898 (f9de579): cibuildwheel v4.1.1 -> v4.2.1 and drop CIBW_ENABLE=cpython-prerelease. v4.1.1 predates CPython 3.15.0rc1; v4.2.1 builds against 3.15.0rc2, which is ABI-compatible with 3.15.0. - Port the workflow part of #3096 (13.4.4): release the 3.15 wheels and remove the 3.15 allow-prereleases and continue-on-error guards, including the Linux one. - Test 3.15 and 3.15t on CUDA 13.4.2 against published cuda-bindings 13.4.4, the first release with cp315 wheels. - Add the Python 3.15 classifier and the 1.2.2 release notes, and list Python 3.10 - 3.15 on the install and support pages.

Current CUPTI and cuSPARSELt wheels ship these names, and the Windows pathfinder all_must_work tests fail without them. 13.4.x carries the same fixes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Support Python 3.15 with CUDA 12 through cuda-bindings 12.9.10 cuda-bindings 12.9.10 adds cp315 wheels, so Python 3.15 is no longer CUDA 13 only. Add CUDA 12.9 Python 3.15 and 3.15t test jobs against the published 12.9.* release, and name both bindings floors in the install page and the 1.2.2 release notes.

Description
cuSPARSELt 0.10.0 renamed the DLL in its CUDA 13 Windows wheel from
cusparseLt.dlltocusparseLt_13.dll. Pathfinder currently searches only for the old name, so it cannot load the library from the new wheel and CUDA Python CI fails.Search for
cusparseLt_13.dllfirst, while retainingcusparseLt.dllas a fallback for older installations.The cuSPARSELt 0.10.0 CUDA 13 Linux wheels for both x86-64 and ARM64 still contain
nvidia/cu13/lib/libcusparseLt.so.0. The existing Linux SONAME and search path remain correct, so no Linux change is needed.
