Enhance JSON file reading and processing

- Update read_json_file to return a list of objects, handling both single and multiple JSON objects.
- Modify merge_objects to include total_files in the statistics.
- Adjust print_summary to display the number of files processed alongside total objects.
- Refactor JSON file reading loop to accumulate objects from multiple files.
