refactor: remove 3,700+ LOC of unused HNSW implementations

Browse source 
Delete dead code island that was never instantiated in production:
- OptimizedHNSWIndex (430 LOC)
- PartitionedHNSWIndex (412 LOC)
- DistributedSearchSystem (635 LOC)
- ScaledHNSWSystem (744 LOC)
- HNSWIndexOptimized (585 LOC)
- brainy-backup.ts stale example (903 LOC)

Also upgrades entry point recovery from O(n) to O(1) using existing
highLevelNodes index structure.

Production uses only: HNSWIndex (memory) and TypeAwareHNSWIndex (persistent)
