fix: correct tool configuration fields in pyproject.toml

- Fix ruff target-version to use Python version specifier (py312) instead of package version
- Fix mypy python_version to use semantic version (3.12) instead of package version
- Fix pytest minversion to use pytest version (7.0) instead of package version
- Add critical comments to prevent future version confusion
- Resolve CI/CD pipeline TOML parse errors
