feat: refactor VFS to use proper Brainy graph relationships

Browse source 
- Replace metadata path queries with brain.getRelations() API
- Use graph traversal for parent-child relationships via VerbType.Contains
- Remove fallback metadata queries - trust graph relationships completely
- Fix getChildren() to properly query relationship graph
- Update getRelated() and getRelationships() to use native Brainy APIs

This enables full graph benefits: indexes, optimizations, and visualizations
now work correctly with VFS. The filesystem structure is now a true graph
using Brainy's native relationship system.
