Add version flag to CLI (#1)

* Add -v/--version flag to CLI

Add a version flag that displays the package version from importlib.metadata.
Both -v and --version are supported. Includes tests for both flags.

* Add uv.lock

* Remove uv.lock and add to .gitignore

* Use importlib.metadata in version tests instead of hardcoded version

* Refactor to use click.version_option decorator

* Simplify version_option using package_name for auto-detection
