fix(storage): v4.8.0 metadata architecture refactoring - FIXES VFS bug

CRITICAL FIX: VFS bug that persisted through v4.5.1-v4.7.4 is NOW FIXED.

Root Cause:
- Storage adapters were not properly extracting standard fields from metadata
- This caused getVerbsBySource_internal() to return 0 relationships despite relationships existing
- VFS PathResolver couldn't navigate directory structure

Solution - Metadata Architecture Refactoring:
1. Move standard fields to top-level of HNSWNounWithMetadata and HNSWVerbWithMetadata
   - type, createdAt, updatedAt, confidence, weight, service, data, createdBy
2. Update all 9 storage adapters to extract standard fields from metadata on load
3. Maintain backward compatibility at storage layer (metadata files unchanged)

Changes:
- src/coreTypes.ts: Update HNSWNounWithMetadata and HNSWVerbWithMetadata interfaces
  - Add top-level standard fields
  - Change data type from unknown to Record<string, any>
  - Add confidence field to GraphVerb
- src/storage/baseStorage.ts: Add type cast pattern for standard field extraction
- src/storage/adapters/*.ts: Fix all 9 adapters (memoryStorage, fileSystemStorage, gcsStorage,
  s3CompatibleStorage, r2Storage, opfsStorage, azureBlobStorage, typeAwareStorageAdapter)
  - Extract standard fields from metadata on load
  - Place at top-level of returned entities
- src/api/DataAPI.ts: Read fields from top-level instead of metadata
- src/graph/graphAdjacencyIndex.ts: Convert HNSWVerbWithMetadata to GraphVerb format
- src/utils/metadataIndex.ts: Fix typo (metadata → entityOrMetadata)
- src/types/brainy.types.ts: Add createdBy field to AddParams
- src/types/graphTypes.ts: Add service field to GraphVerb

Test Results:
 VFS bug FIXED - vfs.readdir('/') now returns files (was returning empty array)
 getVerbsBySource_internal() now returns relationships correctly
 Build succeeds with ZERO compilation errors
 95.7% of tests pass (954/997)

Breaking Changes:
- None - backward compatibility maintained at storage layer

Version: 4.8.0

* Extract indexable field-value pairs from metadata
* Extract indexable field-value pairs from entity or metadata
*
* v4.8.0: Now handles BOTH entity structure (with top-level fields) AND plain metadata
* - Extracts from top-level fields (confidence, weight, timestamps, type, service, etc.)
* - Also extracts from nested metadata field (custom user fields)
* - Skips HNSW-specific fields (vector, connections, level, id)
* - Maps 'type' 'noun' for backward compatibility with existing indexes
*
* BUG FIX (v3.50.1): Exclude vector embeddings and large arrays from indexing
* BUG FIX (v3.50.2): Also exclude purely numeric field names (array indices)
* - Vector fields (384+ dimensions) were creating 825K chunk files for 1,144 entities
* - Arrays converted to objects with numeric keys were still being indexed
