/**
 * MetonaAI Desktop — Electron 主进程入口
 *
 * 启动流程（按架构规范强制顺序）：
 * 1. 初始化日志系统 + 加载 .env 环境变量（P0-4: 应用内配置优先，env 作为回退）
 * 2. 选择/创建工作空间 → 校验必需文件（缺失自动创建）
 * 3. 连接 SQLite → 执行 schema 迁移 → 加载配置
 * 4. 初始化 Provider Adapter（P2-10: AgentEngineManager 管理每会话独立引擎）
 * 5. 加载磁盘文件 → 构建 System Prompt
 * 6. 注册内置工具 + 连接 MCP Servers（P1-11: 等待连接完成再广播就绪）
 * 7. 启动 React UI → Agent 就绪
