* Add ruff * Add ruff config * Add ruff rules that look useful and are already passing * Add more ruff rules after talking with Jonathan * Add line length exception for acceptably long indented line * Resolve ruff line length 88 rule in args. Changing small lines but adding a noqa ignore directive to longer lines that look best as they are. Their dedented length is still less than 88 * poe format * Resolve all remaining ruff line length errors * Replace flake* and isort with ruff calls * Add black --check as final lint step. ruff catches most but not all black formatting issues * Remove unneeded flakeheaven setting * Remove flake* and isort now that ruff is handling all their business * Update pyproject, lockfile with latest version of ruff * Document each ruff rule with comment * Add black --version call before black --check * Remove extraneous period
