feat: implement comprehensive neural clustering system

- Add 7 advanced clustering algorithms (semantic, k-means, DBSCAN, hierarchical, graph, multi-modal, sampling)
- Integrate with existing 31 NounTypes + 40 VerbTypes taxonomy for semantic clustering
- Leverage HNSW index for O(n) hierarchical clustering performance
- Add graph community detection using verb relationships and Louvain modularity
- Implement multi-modal fusion combining vector + graph + semantic signals
- Add Triple Intelligence integration for intelligent cluster labeling
- Support adaptive sampling strategies for large datasets
- Include 150+ utility methods for advanced clustering operations
- Add comprehensive TypeScript definitions and error handling
- Optimize for graph-explorer integration with LOD patterns
