Pull request overview

This PR modernizes the project’s build/release pipeline around pyproject.toml + scikit-build-core, adds repo linting checks, and updates CI to build distributable wheels (including manylinux) across multiple Python versions while bumping the package version to 1.5.0.

Changes:

• Migrate packaging from setup.py to pyproject.toml (scikit-build-core/CMake) and update docs/manifests accordingly.
• Add CI workflows to build/release wheels across Python 3.10–3.14 (manylinux for Linux) and introduce repo-wide Black/Flake8 checks as tests.
• Reformat/clean up Python code and test-data generation scripts; bump version to 1.5.0.
