refactor: Standardize naming conventions (#47)

* refactor: Standardize naming conventions

* chore: Update the version and re-run experiments

* chore: Improve code quality tooling and documentation

- Add pre-commit job to CI workflow for automated linting on PRs
- Update uniface/__init__.py with copyright header, module docstring,
  and logically grouped exports
- Revise CONTRIBUTING.md to reflect pre-commit handles all formatting
- Remove redundant ruff check from CI (now handled by pre-commit)
- Update build job Python version to 3.11 (matches requires-python)
