feat: enhance pre-push hook with changelog preview and user confirmation

- Updated the pre-push hook to display a preview of the changelog and the new version before proceeding with the push.
- Added color-coded output for better visibility and user experience.
- Implemented user confirmation to abort the push if the changelog preview is not approved.
- Cleaned up temporary files created during the changelog update process.
