ci: add pre-commit config with ruff linting and formatting (#130)

* ci: add pre-commit config with ruff linting and formatting

Add .pre-commit-config.yaml with:
- ruff: lint checking with auto-fix (matches CI lint.yml)
- ruff-format: code formatting
- Standard file checks: trailing whitespace, end-of-file,
  TOML/YAML validity, merge conflict markers

* style: apply ruff formatting to 3 files

Auto-formatted by ruff-format:
- aw_core/util.py
- tests/test_query2.py
- tests/utils.py
