Add pyproject and pre-commit config

Introduce a `pyproject.toml` with project metadata, runtime dependencies, and Ruff/pyproject-fmt settings, and add a matching `.pre-commit-config.yaml` to enforce basic file checks, pyproject validation, and formatting/linting. Also normalize `.gitignore` with a trailing newline.
