fix: Remove duplicate inference result logging to prevent terminal spam

- Comment out print() statements in InferencePipeline that duplicate GUI callback output
- Prevents each inference result from appearing multiple times in terminal
- Keeps logging system clean while maintaining GUI formatted display
- This was causing terminal output to show each result 2-3 times due to:
  1. InferencePipeline print() statements captured by StdoutCapture
  2. Same results formatted and sent via terminal_output callback
