chore(ci): skip Python 3.14 testing

[gforsyth]

Python 3.14 support is blocked by several segfaulting tests (#414)

Write-up and suggested path forward documented in https://github.com/rapidsai/build-infra/issues/348

To avoid blocking Python 3.14 support for the rest of the release (for rapidsai/build-planning#205), adding skips to the build and test jobs here so we don't test on Python 3.14.

Greptile Summary

Adds map(select(.PY_VER != "3.14")) | to jq matrix_filter expressions across all three CI workflow files to skip Python 3.14 builds and tests while a segfault issue is resolved.

• All test jobs (conda-python-tests, wheel-tests-pylibwholegraph, wheel-tests-cugraph-pyg) in both pr.yaml and test.yaml are updated consistently.
• The wheel-build-cugraph-pyg build job in build.yaml and pr.yaml is updated to avoid building a wheel that would then fail testing.
• wheel-build-libwholegraph (a C++ package using max_by(.PY_VER...)) is intentionally left unfiltered — it has no downstream test job, so even if Python 3.14 is selected as the build environment, no test failures can result. This is consistent with the stated scope of the issue (segfaulting tests).
• wheel-build-pylibwholegraph uses min_by(.PY_VER...) and will not select 3.14, so no change is needed there.

Confidence Score: 5/5

• Safe to merge — minimal, targeted changes with no logic errors.
• All test jobs across the three workflow files have been updated with consistent 3.14 exclusion filters. The jq syntax is correct. Build jobs omitted from the filter either use min_by(.PY_VER...) (safe) or are C++ packages with no downstream test stage.
• No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/build.yaml	Adds Python 3.14 exclusion to wheel-build-cugraph-pyg. The wheel-build-libwholegraph job (cpp package, uses max_by(.PY_VER...)) is intentionally left unchanged since it has no test stage and failures are test-only.
.github/workflows/pr.yaml	Adds Python 3.14 exclusion to conda-python-tests, wheel-tests-pylibwholegraph, wheel-build-cugraph-pyg, and wheel-tests-cugraph-pyg. wheel-build-libwholegraph (cpp, max_by filter) left unchanged.
.github/workflows/test.yaml	Adds Python 3.14 exclusion to all three test jobs: conda-python-tests, wheel-tests-pylibwholegraph, and wheel-tests-cugraph-pyg. All test jobs in this file are covered.
