feat: fix verb storage pipeline and implement relationship-aware neural clustering
- Add atomic verb saving with rollback on metadata creation failures - Implement missing getVerbsForNoun() method required by neural APIs - Fix broken FileSystemStorage filter methods that returned empty arrays - Add scalable clustersWithRelationships() method with batching for millions of nodes - Enhance error handling and logging throughout verb storage pipeline - Add comprehensive relationship analysis with intra/inter-cluster edges - Improve API consistency between noun and verb methods 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
