- Introduced `pyproject.toml` to centralize backend tool configurations (e.g., Ruff, mypy, coverage, pytest). - Replaced Black, isort, and Flake8 with Ruff for linting, formatting, and import sorting. - Updated `requirements.txt` to include Ruff and remove replaced tools. - Added `Makefile` to streamline development workflows with commands for linting, formatting, type-checking, testing, and cleanup.
