Clean up verbose logging in grounding metadata implementation

- Remove debug logging from grounding metadata event handlers
- Simplify logging in _process_grounding_metadata method
- Clean up example file logging for better readability
- Remove verbose event parsing comments

Based on suggestions from draft PR #2121
