* Fix mypy errors and apply ruff formatting across packages Fix ast.FunctionDef calls missing type_params for Python 3.12+, correct type: ignore error codes in _comparator and _plugin, and run ruff format on all package source and test files. * Switch CI to prek for lint/typecheck checks Use j178/prek-action for consistent lint+typecheck (ruff check, ruff format, interrogate, mypy) matching local pre-commit config. Keep test as a separate parallel job for test-env support.
