AI Summary: Create a PyInstaller hook for the `uuid6` library. The hook should conditionally use `copy_metadata` based on the `uuid6` version to ensure metadata is correctly included in the bundled application. This involves creating a new hook file, adding the appropriate copyright header, writing tests (if feasible), running the linter, and submitting a pull request following the project's contribution guidelines.
