ci: add pre-commit configuration and workflow

- Add `.pre-commit-config.yaml` to configure hooks for:
  - Standard file checks (trailing whitespace, EOF fixer, YAML check, large files)
  - `nbstripout` for Jupyter notebooks
  - `ruff` for linting
  - `black` for formatting
- Add `.github/workflows/pre-commit.yml` to enforce checks on push and pull requests.
