debug: Add comprehensive debug output and test signals

- Add time import for test result generation
- Add test signal emissions to verify GUI connection works
- Add debug prints for signal establishment
- Test both result_updated and terminal_output signals
- This will help identify if the issue is signal connection or data flow
