feat: Brainy 3.0 - Triple Intelligence Release
BREAKING CHANGE: New unified API for vector, graph, and document search
Major Changes:
- NEW: brain.add() replaces brain.addNoun()
- NEW: brain.find() replaces brain.search()
- NEW: brain.relate() replaces brain.addVerb()
- NEW: brain.update() replaces brain.updateNoun()
- NEW: brain.delete() replaces brain.deleteNoun()
Features:
- Triple Intelligence™ engine (vector + graph + document)
- 31 NounTypes × 40 VerbTypes for universal knowledge modeling
- Zero-config parameter validation
- Enhanced augmentation system (cache, display, metrics)
- <10ms search performance with HNSW indexing
- Full TypeScript type safety
Infrastructure:
- Comprehensive test suites for find() and neural APIs
- Fixed neural API internal calls (getNoun → get)
- Updated README with accurate 3.0 examples
- ESLint v9 configuration
- Structured logging framework
