- Added `BaseStorage` abstract class to provide common functionality for storage adapters.
- Implemented `FileSystemStorage` adapter for Node.js environments, supporting persistent file-based storage.
- Added directory structure management methods to `FileSystemStorage` (`ensureDirectoryExists`, `clear`, etc.).
- Implemented `MemoryStorage` adapter for in-memory storage suitable for non-persistent environments.
- Supported CRUD operations for nouns, verbs, and metadata in both `FileSystemStorage` and `MemoryStorage`.
- Included utility methods like `mapToObject` for serialization and deserialization of complex data structures.
Purpose: Provide extensible, reusable storage solutions with both persistent and non-persistent options for diverse application needs.
