gosmee: migrate to finalAttrs pattern and add best practices

- Use finalAttrs pattern instead of rec for better self-referencing
- Change rev to tag for more semantic git fetching
- Add versionCheckHook to verify binary functionality post-install
- Add nix-update-script for automated version updates
- Add changelog URL and mainProgram to meta
- Improve consistency with modern nixpkgs patterns (following lazyworktree)
