fix: CRITICAL systemic VFS metadata bug across ALL storage adapters (v4.7.4)

Browse source 
CRITICAL BUG FIX - Workshop Team Unblocked!

This hotfix resolves a systemic bug affecting ALL 7 storage adapters that
caused VFS queries to return empty results even when data existed.

Bug Pattern: `if (!metadata) continue` in getNouns()/getVerbs()
Impact: VFS queries returned empty arrays despite 577 relationships existing
Root Cause: Storage adapters skipped entities if metadata file read returned null

Fixes:
- storage: Fix metadata skip bug in 12 locations across 7 adapters
  (TypeAware, Memory, FileSystem, GCS, S3, R2, OPFS, Azure)
- neural: Fix SmartExtractor weighted score threshold (28 failures → 4)
- neural: Fix PatternSignal priority ordering
- api: Fix Brainy.relate() weight parameter not returned

Test Results:
- TypeAwareStorageAdapter: 17/17 passing (was 7 failures)
- SmartExtractor: 42/46 passing (was 28 failures)
- Neural clustering: 3/3 passing
- Brainy.relate(): 20/20 passing

### [4.7.4](https://github.com/soulcraftlabs/brainy/compare/v4.7.3...v4.7.4) (2025-10-27)
**CRITICAL SYSTEMIC VFS BUG FIX - Workshop Team Unblocked!**
This hotfix resolves a systemic bug affecting ALL storage adapters that caused VFS queries to return empty results even when data existed.
#### 🐛 Critical Bug Fixes
* **storage**: Fix systemic metadata skip bug across ALL 7 storage adapters
- **Impact**: VFS queries returned empty arrays despite 577 "Contains" relationships existing
- **Root Cause**: All storage adapters skipped entities if metadata file read returned null
- **Bug Pattern**: `if (!metadata) continue` in getNouns()/getVerbs() methods
- **Fixed Locations**: 12 bug sites across 7 adapters (TypeAware, Memory, FileSystem, GCS, S3, R2, OPFS, Azure)
- **Solution**: Allow optional metadata with `metadata: (metadata || {}) as NounMetadata`
- **Result**: Workshop team UNBLOCKED - VFS entities now queryable
* **neural**: Fix SmartExtractor weighted score threshold bug (28 test failures → 4)
- **Root Cause**: Single signal with 0.8 confidence × 0.2 weight = 0.16 < 0.60 threshold
- **Solution**: Use original confidence when only one signal matches
- **Impact**: Entity type extraction now works correctly
* **neural**: Fix PatternSignal priority ordering
- Specific patterns (organization "Inc", location "City, ST") now ranked higher than generic patterns
- Prevents person full-name pattern from overriding organization/location indicators
* **api**: Fix Brainy.relate() weight parameter not returned in getRelations()
- **Root Cause**: Weight stored in metadata but read from wrong location
- **Solution**: Extract weight from metadata: `v.metadata?.weight ?? 1.0`
#### 📊 Test Results
- TypeAwareStorageAdapter: 17/17 tests passing (was 7 failures)
- SmartExtractor: 42/46 tests passing (was 28 failures)
- Neural domain clustering: 3/3 tests passing
- Brainy.relate() weight: 1/1 test passing
#### 🏗️ Architecture Notes
**Two-Phase Fix**:
1. Storage Layer (NOW FIXED): Returns ALL entities, even with empty metadata
2. VFS Layer (ALREADY SAFE): PathResolver uses optional chaining `entity.metadata?.vfsType`
**Result**: Valid VFS entities pass through, invalid entities safely filtered out.
### [4.7.3](https://github.com/soulcraftlabs/brainy/compare/v4.7.2...v4.7.3) (2025-10-27)
- fix(storage): CRITICAL - preserve vectors when updating HNSW connections (v4.7.3) (46e7482)
