The __words__ keyword index stores 50-5000 entries per entity (one per
word), which inflated avg entries/entity well above the corruption
threshold of 100. This caused:
1. validateConsistency() to falsely detect corruption on every startup,
triggering unnecessary clearAllIndexData() + rebuild() cycles
2. getStats() to log false "Metadata index may be corrupted" warnings
and report inflated totalEntries/totalIds stats
Both methods now skip __words__ when counting, so stats and health
checks reflect metadata fields only (noun, type, createdAt, etc.).
Keyword search is unaffected since the __words__ field index itself
is not modified.
HistoricalStorageAdapter was looking for underscore-prefixed properties
(_commitLog, _blobStorage, _treeObject) but BaseStorage sets them without
underscores (commitLog, blobStorage). This caused all asOf() calls to fail.
Changes:
- Fix property access: use commitLog/blobStorage instead of _commitLog/_blobStorage
- Remove unused treeObject property (TreeObject is dynamically imported)
- Remove unused TreeObject static import

Workshop team reported that brain.clear() doesn't fully delete persistent storage.
After calling clear() and creating a new Brainy instance, all data was restored
from storage. This is a CRITICAL data integrity bug.
Root causes (3 bugs fixed):
1. **FileSystemStorage deleting wrong directory**: Data stored in branches/main/entities/
but clear() was only deleting old pre-v5.4.0 structure (nouns/, verbs/, metadata/)
2. **COW reinitialization after clear()**: Setting cowEnabled=false on old instance
doesn't affect new instances. Fixed with persistent marker file.
3. **Metadata index cache not cleared**: find() with type filters returned stale data
after clear(). Fixed by recreating MetadataIndexManager.
Changes:
- FileSystemStorage: Clear branches/ directory (where data actually lives)
- All storage adapters: Add checkClearMarker()/createClearMarker() methods
- BaseStorage: Check for cow-disabled marker before initializing COW
- Brainy: Recreate metadataIndex after clear() to flush cached data
- Tests: Comprehensive regression suite (8 tests) to prevent recurrence
