cleanup: Archive old complex scripts and documentation
- Move all old complex backup scripts to old_scripts/ - Archive previous documentation versions - Clean up temporary files and debian packages - Update README to focus on new simple system - Keep only the enhanced simple backup system in main directory Main directory now contains only: - simple_backup_gui.py (GUI interface) - enhanced_simple_backup.sh (CLI interface) - list_drives.sh (helper) - simple_backup.sh (basic CLI) - SIMPLE_BACKUP_README.md (detailed docs) - README.md (project overview)
