fix: enable IntelligentVerbScoring by default as core functionality

- Change category from 'premium' to 'core' - this is essential relationship quality improvement
- Enable by default (enabled: true) instead of disabled by default
- Fix contradictory documentation that claimed "enabled by default" but implemented "disabled by default"
- Update reference condition to handle new default behavior properly
- Update comment from "Enhancement features" to "Core relationship quality features"

This aligns the implementation with the documented intent and provides better
relationship quality out of the box without requiring explicit configuration.
