/**
 * MAMA Memory Store - Compatibility Wrapper
 *
 * This file now serves as a compatibility layer that re-exports db-manager functions.
 * The actual database logic has been moved to db-manager.js which supports both
 * SQLite (local development) and PostgreSQL (Railway production).
 *
 * Migration Note:
 * - Old: memory-store.js directly used better-sqlite3 + sqlite-vss
 * - New: memory-store.js → db-manager.js → db-adapter (SQLite or PostgreSQL)
 *
 * All MAMA modules can continue to require('memory-store') without changes.
 *
 * @module memory-store
 * @version 2.0
 * @date 2025-11-17
