任务调度用数据库锁做轻量分布式协调：多个实例轮询时，只有抢到 lock_owner + lock_until 的实例能执行。
锁不是永久锁，任务失败或实例异常后可以靠 lock_until 自动释放。
锁时长交给部署配置，避免长任务超过固定 30 分钟后被其他实例重复执行 SQL/生成报告。
普通聊天保留 ask_user 挂起能力；定时任务关闭人工追问能力，让 Agent 自己判断无法完成并结束。
强约束放在工具层，prompt 只作为行为提示，不作为可靠控制边界。
主要修改
新增了定时任务的后端 CRUD、实体、Mapper、调度器、下次执行时间计算逻辑，以及前端定时任务管理页。调度器负责轮询到期任务、抢锁、异步执行、完成后计算下一次运行时间。AgentService 和 AskUserTool 增加了 allowUserPrompt 执行上下文，用来区分普通会话和定时任务。
