- Implement 7 core unified API methods (add, search, import, addNoun, addVerb, update, delete)
- Add universal encryption system with encryptData/decryptData methods
- Add container deployment support with model preloading
- Implement soft delete by default for better performance
- Add searchVerbs() and getNounWithVerbs() for graph traversal
- Reduce package size by 16% despite major feature additions
- Create comprehensive CHANGELOG.md and MIGRATION.md
- Consolidate CLI from 40+ to 9 clean commands
- All scaling optimizations preserved and enhanced

BREAKING CHANGES:
- addSmart() method removed (use add() - smart by default)
- CLI commands consolidated and renamed
- Pipeline classes unified into single Cortex class

This is the complete 1.0 release candidate with all planned features implemented and tested.
