chore: Enhance git hook setup with executable permissions and submodule alias

- Add chmod +x to ensure pre-push hook is executable after creation
- Add global git alias 'sc-commit' for committing to all submodules at once
- Improve user feedback with detailed explanation of installed components
- Better code organization with clearer comments

This makes the setup script more robust by ensuring the hook has proper permissions and provides a convenient command for bulk submodule commits.
