- Add project metadata with Python 3.11+ requirement
- Configure dependencies: python-telegram-bot, sqlalchemy, httpx, aiosqlite
- Add dev dependencies: pytest, pytest-cov, pytest-asyncio, ruff, pre-commit
- Configure ruff with line-length 100, py311 target
- Configure pytest with asyncio_mode auto
- Use hatchling build backend with src layout
