Replace black and flake8 with ruff - #218

Conversation
Drop autoblack.yml and the flake8 lint job; add formatting.yml running 'ruff check' and 'ruff format --check' via astral-sh/ruff-action, and swap the severe-error gate in run_tests.yml from flake8 to ruff. Apply 'ruff format' and 'ruff check --fix' (import sorting) across the package and tests. Notebooks stay excluded, matching the previous black 'jupyter: false' setup.
