Hide Hooks installation from CLI until implementation is ready

- Commented out HooksComponent import and export in __init__.py
- Removed hooks from --components all installation list
- Set enabled=false in features.json configuration
- Updated descriptions to indicate "NOT YET IMPLEMENTED"
- Code remains intact for future re-enablement

The Hooks system is not yet fully implemented, so hiding it from
users prevents confusion while preserving the framework for future use.
