Fix release wheel pipeline to emit binary extensions for macOS arm64

[Copilot]

The release workflow was failing on macos-14/arm64 during delocate-wheel because built wheels did not contain architecture-matching binary extensions. This updates packaging/build configuration so cibuildwheel consistently produces binary wheels with compiled Cython modules.

• Packaging: ensure extension build path is active

  • In pyproject.toml, enabled Poetry setup-file generation for wheel builds:
    • generate-setup-file = true
  • Added setuptools to build-system requirements (with minimum bound) so generated setup-based extension builds can run in isolated build envs:
    • setuptools>=61.0

• Release workflow: make cibuildwheel frontend/deps explicit

  • In .github/workflows/create-release.yml, set:
    • CIBW_BUILD_FRONTEND: build
    • CIBW_BEFORE_BUILD: python -m pip install --upgrade pip "Cython>=3.0" "numpy>=1.8"

• Resulting behavior

  • Wheel builds now follow an explicit frontend + dependency bootstrap path and include compiled extension artifacts instead of producing effectively pure-Python wheels on arm64.
