后端重构： - 新增分层架构：API Routes -> Services -> Repositories -> Infrastructure - 彻底移除全局单例，全面采用 FastAPI 依赖注入 - 新增 api/ 目录拆分路由（proxies, plugins, scheduler, settings, stats） - 新增 services/ 业务逻辑层：ProxyService, PluginService, SchedulerService, ValidatorService, SettingsService - 新增 repositories/ 数据访问层：ProxyRepository, SettingsRepository, PluginSettingsRepository - 新增 models/ 层：Pydantic Schemas + Domain Models - 重写 core/config.py：采用 Pydantic Settings 管理配置 - 新增 core/db.py：基于 asynccontextmanager 的连接管理，支持数据库迁移 - 新增 core/exceptions.py：统一业务异常体系 插件系统重构（核心）： - 新增 core/plugin_system/：BaseCrawlerPlugin + PluginRegistry - 采用显式注册模式（装饰器 + plugins/__init__.py），类型安全、测试友好 - 新增 plugins/base.py：BaseHTTPPlugin 通用 HTTP 爬虫基类 - 迁移全部 7 个插件到新架构（fate0, proxylist_download, ip3366, ip89, kuaidaili, speedx, yundaili） - 插件状态持久化到 plugin_settings 表 任务调度重构： - 新增 core/tasks/queue.py：ValidationQueue + WorkerPool - 解耦爬取与验证：爬虫只负责爬取，代理提交队列后由 Worker 异步验证 - 调度器定时从数据库拉取存量代理并分批投入验证队列 前端调整： - 新增 frontend/src/services/ 层拆分 API 调用逻辑 - 调整 stores/ 和 views/ 使用 Service 层 - 保持 API 兼容性，页面无需大幅修改 其他： - 新增 main.py 作为新入口 - 新增 DESIGN.md 架构设计文档 - 更新 requirements.txt 增加 pydantic-settings
