//! SurrealDB database implementation for version 2.3+
//!
//! This module provides a complete SurrealDB implementation of the Database trait.
//! It supports both embedded (in-memory and RocksDB) and network modes.
//!
//! Enabled with the `surrealdb` feature (enabled by default).
//!
//! # Features
//!
//! - Full async/await support with SurrealDB 2.3+
//! - Automatic schema initialization
//! - Type-safe queries via serde
//! - Support for all database operations
//!
//! # Examples
//!
//! ```ignore
//! // Create in-memory database (testing)
//! let db = SurrealDatabase::new_memory().await?;
//!
//! // Create file-based database
//! let db = SurrealDatabase::new_file("workspace.surreal").await?;
//! ```
