feat: Enhance Cursor Linux ID modifier with improved config generation and validation

- Simplified machine ID generation by directly combining prefix and random ID
- Improved sed escape function to handle special characters
- Added JSON configuration file validation using jq
- Implemented fallback mechanism to restore backup if config is invalid
- Streamlined machine ID and device ID generation process
