- 删除 ValidationQueue 双轨持久化队列，替换为纯内存 AsyncWorkerPool - 引入统一后台任务框架 JobExecutor（Job/CrawlJob/ValidateAllJob） - 新增 PluginRunner 统一插件执行（超时、重试、健康检查、统计） - 重构 SchedulerService 职责收敛为仅定时触发 ValidateAllJob - 使用 AsyncExitStack 重构 lifespan，安全管理长生命周期资源 - 路由层瘦身 50%+，业务异常上抛由全局中间件统一处理 - 实现设置全热更新（WorkerPool 并发、Validator 超时即时生效） - 前端 Store 强制写后重新拉取，消除乐观更新数据不同步 - 删除 queue.py / task_repo.py / task_service.py - 新增 execution 单元测试，全部 85 个测试通过
