feat(platform): Implement platform infrastructure with cloud-native support
- Add storage service (LocalAdapter + OSSAdapter stub) - Add database connection pool with graceful shutdown - Add logging system with winston (JSON format) - Add environment config management - Add async job queue (MemoryQueue + DatabaseQueue stub) - Add cache service (MemoryCache + RedisCache stub) - Add health check endpoints for SAE - Add monitoring metrics for DB, memory, API Key Features: - Zero-code switching between local and cloud environments - Adapter pattern for multi-environment support - Backward compatible with legacy modules - Ready for Aliyun Serverless deployment Related: Platform Infrastructure Planning (docs/09-鏋舵瀯瀹炴柦/04-骞冲彴鍩虹璁炬柦瑙勫垝.md)

* - ✅ 云端部署：从SAE环境变量加载
|

* - ✅ 统一配置管理，避免散落各处
|

* - ✅ 启动时验证必需配置

* 环境变量优先级：
|

* 1. 系统环境变量（最高优先级，云端部署）
|
||||
* 2. .env文件（本地开发）
|

* 3. 默认值（兜底）
