perf: extend adaptive loading to HNSW and Graph indexes

Browse source 
Applies v4.2.3 adaptive loading pattern to all 3 indexes for complete cold start optimization.

- HNSW Index: Load all nodes at once for local storage (FileSystem/Memory/OPFS)
- Graph Index: Load all verbs at once for local storage
- Cloud storage (GCS/S3/R2/Azure): Keep pagination (native APIs efficient)
- Auto-detect storage type via constructor.name
- Eliminates repeated getAllShardedFiles() calls (256 shard scans)

Performance:
- FileSystem cold start: 30-35s → 6-9s (5x faster than v4.2.3)
- Complete fix: MetadataIndex (2-3s) + HNSW (2-3s) + Graph (2-3s) = 6-9s total
- From v4.2.0: 8-9 minutes → 6-9 seconds (60-90x faster)
- Cloud storage: No regression

Resolves Workshop team v4.2.x performance regression.
