CHECKPOINT: Brainy 2.0 API refactor - pre-fixes state

Current state:
- Unified augmentation system to BrainyAugmentation interface
- Changed methods to specific noun/verb naming (addNoun, getNoun, etc)
- Made old methods private
- Combined getNouns into single unified method
- Neural API exists and is complete
- Triple Intelligence uses correct Brainy operators (not MongoDB)

Issues identified:
- Documentation incorrectly shows MongoDB operators (code is correct)
- Need to ensure all features are properly exposed
- Need to verify nothing was lost in simplification

This commit serves as a rollback point before applying fixes.
