Add comprehensive ruff linting rules and migrate to uv build backend

- Configure ruff with strict linting rules (pycodestyle, pyflakes, isort, pylint, etc.)
- Exclude notebooks folder from linting
- Set line length to 88 characters and target Python 3.13
- Migrate build backend from hatchling to uv_build for better integration
- Add per-file ignores for __init__.py and scripts
