Merge started

Your change will be merged immediately since you used the force (-f) flag, bypassing any CI checks (ETA: 1-5 minutes). Please use -f as last resort and instead consider -i/--ignore-current to continue the merge ignoring current failures. This will allow currently pending tests to finish and report signal before the merge.

## Summary Skip XPU manywheel builds for Python 3.15 / 3.15t in the same way #184600 skipped ROCm. Triton XPU 3.15 wheel builds are currently broken (see the exclusion in `.github/workflows/build-triton-wheel.yml`); without working triton-xpu, manywheel XPU 3.15 builds cannot link triton and fail. ## Change `.github/scripts/generate_binary_build_matrix.py` — adds 8 lines mirroring the ROCm skip block: ```py # TODO: Re-enable XPU for python 3.15 once the triton XPU 3.15 # wheel build is fixed (tracked in #184901).
