//! Storage engine for Engram
//!
//! Handles SQLite database operations, WAL mode, and schema management.
//!
//! # Architecture (ENG-14)
//!
//! The storage layer is built around the `StorageBackend` trait which defines
//! the interface for all storage operations. This allows for multiple backend
//! implementations:
//!
//! - `SqliteBackend` - Current default, uses rusqlite with WAL mode
//! - `TursoBackend` - Planned for Phase 6, distributed SQLite
//! - `MeilisearchBackend` - Planned for Phase 7, full-text search focused
//!
//! ## Extension Traits
//!
//! - `TransactionalBackend` - For backends that support ACID transactions
//! - `CloudSyncBackend` - For backends with cloud synchronization
