Pull request overview

This PR modernizes the project’s Python packaging and developer tooling configuration by moving requirements and build metadata into pyproject.toml, tightening static analysis settings, and aligning the codebase with lint expectations (module-level docstrings).

Changes:

• Migrate dev/test dependency management from dev_requirements.txt / tests/requirements.txt into pyproject.toml extras and update CI installation accordingly.
• Remove legacy packaging files (setup.py, MANIFEST.in) and switch to dynamic versioning via featuremanagement._version.VERSION.
• Add module-level docstrings across the package and set mypy to fully strict mode.
