### Minor Changes

- [#410](https://github.com/esengine/esengine/pull/410) [`71022ab`](https://github.com/esengine/esengine/commit/71022abc99ad4a1b349f19f4ccf1e0a2a0923dfa) Thanks [@esengine](https://github.com/esengine)! - feat: add database layer architecture

    Added new database packages with layered architecture:

    **@esengine/database-drivers (Layer 1)**
    - MongoDB connection with pool management, auto-reconnect, events
    - Redis connection with auto-reconnect, key prefix
    - Type-safe `IMongoCollection<T>` interface decoupled from mongodb types
    - Service tokens for dependency injection (`MongoConnectionToken`, `RedisConnectionToken`)

    **@esengine/database (Layer 2)**
    - Generic `Repository<T>` with CRUD, pagination, soft delete
    - `UserRepository` with registration, authentication, role management
    - Password hashing utilities using scrypt
    - Query operators: `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$in`, `$nin`, `$like`, `$regex`

    **@esengine/transaction**
    - Refactored `MongoStorage` to use shared connection from `@esengine/database-drivers`
    - Removed factory pattern in favor of shared connection (breaking change)
    - Simplified API: `createMongoStorage(connection, options?)`

    Example usage:

    ```typescript
    import { createMongoConnection } from '@esengine/database-drivers';
    import { UserRepository } from '@esengine/database';
    import { createMongoStorage, TransactionManager } from '@esengine/transaction';

    // Create shared connection
    const mongo = createMongoConnection({
        uri: 'mongodb://localhost:27017',
        database: 'game'
    });
    await mongo.connect();

    // Use for database operations
    const userRepo = new UserRepository(mongo);
    await userRepo.register({ username: 'john', password: '123456' });

    // Use for transactions (same connection)
    const storage = createMongoStorage(mongo);
    const txManager = new TransactionManager({ storage });
    ```
