feat: ID-first storage architecture + remove memory-unsafe APIs (v6.0.0)

BREAKING CHANGES:

**ID-First Storage Paths**
- Direct O(1) entity access without type lookups
- Before: entities/nouns/{TYPE}/metadata/{SHARD}/{ID}.json
- After:  entities/nouns/{SHARD}/{ID}/metadata.json
- Migration handled automatically on first init()

**Removed Memory-Unsafe APIs**
- Removed brain.merge() - loaded all entities into memory
- Removed brain.diff() - loaded all entities into memory
- Removed brain.data().backup() - loaded all entities into memory
- Removed brain.data().restore() - depended on backup()
- Removed CLI commands: backup, restore, cow merge

**Migration Paths**
- merge() → Use checkout() or manually copy entities with pagination
- diff() → Use asOf() with manual paginated comparison
- backup() → Use fork() for instant COW snapshots
- restore() → Use checkout() to switch to snapshot branch

Core Improvements:
-  All 8 storage adapters properly call super.init()
-  GraphAdjacencyIndex integration in BaseStorage.init()
-  Fixed ID-first path bugs (vector.json → vectors.json)
-  Fixed MemoryStorage.initializeCounts() for ID-first paths
-  New VFS APIs: du(), access(), find()
-  Comprehensive documentation with migration guides

Storage Adapters Fixed:
- MemoryStorage, FileSystemStorage, AzureBlobStorage
- GCSStorage, R2Storage, S3CompatibleStorage
- OPFSStorage, HistoricalStorageAdapter
