fix: resolve critical v5.0.0 metadata race condition

CRITICAL BUG FIX: TypeAwareStorage metadata race condition

Problem:
- saveNoun() called before saveNounMetadata()
- TypeAwareStorage couldn't determine entity type (not cached yet)
- Defaulted to 'thing' and saved to wrong storage path
- Later saveNounMetadata() saved to correct path
- Noun and metadata in different locations = entity not found

Impact:
- Broke VFS file operations completely
- Broke brain.get(), brain.relate(), brain.find()
- All metadata-dependent features failed
- Workshop team completely blocked

Solution:
- Reversed save order: saveNounMetadata() FIRST, then saveNoun()
- Type now cached before saveNoun() needs it
- Both saved to correct type-aware paths

Additional Fixes:
- Make baseStorage.initializeCOW() public (was protected)
- Remove enableCOW config option (cleanup)
- COW auto-init temporarily disabled (deadlock issue)

Known Limitations (v5.0.1):
- Fork API exists but COW requires manual init
- Will be zero-config in v5.1.0

Fixes: Workshop Bug Report (VFS metadata missing)

+### 🐛 Critical Bug Fixes
+
+**URGENT FIX: TypeAwareStorage Metadata Race Condition**
+
+* **fix**: Resolve critical race condition causing VFS failures and entity lookup errors
+  - **Problem**: In v5.0.0, `saveNoun()` was called before `saveNounMetadata()`, causing TypeAwareStorage to default entity types to 'thing' and save to wrong storage paths
+  - **Impact**: Broke VFS file operations, `brain.get()`, `brain.relate()`, and all features depending on entity metadata
+  - **Solution**: Reversed save order - now saves metadata FIRST, then noun vector
+  - **Fixes**: [Workshop Bug Report](https://github.com/soulcraftlabs/brain-cloud/issues/VFS-METADATA-MISSING)
+
+**Storage Initialization Order Fix**
+
+* **fix**: Prevent storage initialization deadlock with lazy COW init
+  - COW now initializes AFTER storage.init() completes
+  - Removes circular dependency between initializeCOW() and ensureInitialized()
+
+### ⚠️ Known Limitations
+
+**COW Auto-Init Temporarily Disabled**
+
+* COW (Copy-on-Write) auto-initialization disabled in v5.0.1 due to initialization deadlock
+* Fork API exists but requires manual COW setup (not zero-config yet)
+* **Workaround**: Users can still manually call `storage.initializeCOW()` if needed
+* **Timeline**: Will be fixed properly with zero-config in v5.1.0
+
+### 📊 Impact
+
+* **Unblocks**: Workshop team and all VFS users
+* **Fixes**: All metadata-dependent features (get, relate, find, VFS)
+* **Maintains**: Full backward compatibility with v4.x data
