chore(release): 6.3.0 - singleton GraphAdjacencyIndex architecture fix

Critical architectural fix for VFS tree corruption bug:
- GraphAdjacencyIndex singleton via storage.getGraphIndex()
- Auto-rebuild verbIdSet when LSM-trees have existing data
- Removed dual-ownership causing verbIdSet out of sync
- PathResolver cache invalidation on checkout/fork
