如何做到先初始化完全局规则，后根据业务场景动态对请求data进行校验？

当前流程：
1.初始化engine
2.初始化datacontext
3.用datacontext加载规则
4.使用规则对数据进行判定

典型需求是先对规则完成初始化，全局加载，然后不同代码场景动态的地对请求data进行规则判定，即是实现：
1->4
2->3
2->3

不然每次检查数据，都需要完成2,3,4，规则不停重建，有什么方式能实现呢？

Start by reading the engine and datacontext flow described in the issue, especially how rules are loaded and applied. Determine whether rules can be initialized globally and reused across request-scoped validation; done means supporting the 1→4 and repeated 2→3 flow without rebuilding rules for every check.
