fix(versioning): clean architecture with index pollution prevention

Browse source 
v6.3.0 Versioning System Overhaul:
- Rewrite VersionIndex to use pure key-value storage (not entities)
- Fix restore() to use brain.update() - updates all indexes (HNSW, metadata, graph)
- Remove 525 LOC dead code (versioningAugmentation.ts - untested, unused)
- Fix branch isolation in tests (fork() vs checkout() semantics)

Key improvements:
- Versions no longer pollute find() results
- restore() properly updates all indexes
- 75 tests passing (60 unit + 15 integration)
- Net reduction of ~290 lines while fixing bugs
