重大重构：引擎模块拆分 + P0插件实现 + 55个Bug修复

核心变更:
- engine.py(1781行)拆分为8个独立模块: lifecycle/security/deps/
  datastore/pl_injector/watcher/signature/manager
- 新增plugin-bridge: 事件总线 + 服务注册 + RPC通信
- 新增i18n: 国际化/多语言翻译支持
- 新增plugin-storage: 插件键值/文件存储
- 新增ws-api: WebSocket实时通信(pub/sub + 自定义处理器)
- nodejs-adapter统一为Plugin ABC模式

Bug修复:
- 修复load_all()中store_dir未定义崩溃
- 修复DependencyResolver入度计算(拓扑排序)
- 修复PermissionError隐藏内置异常
- 修复CORS中间件头部未附加到响应
- 修复IntegrityChecker跳过__pycache__目录
- 修复版本号不一致(v2.0.0→v1.2.0)
- 修复测试文件的Logger导入/路径/私有方法调用
- 修复context.py缺少typing导入
- 修复config.py STORE_DIR默认路径(./mods→./store)

测试覆盖: 14→91个测试, 全部通过
