Rule Ts incorrect

The `rule.js` recently refactored the `rule.event` property to `rule.ruleEvent` (80e84b3ada7df7fca20aba21e37d8b5ee4257023) but there were no corresponding updates to the types when using the types accessing the property directly does not work as expected.

Should the type use `rule.ruleEvent` or should it use accessors for the event?

js & ts are not my speciality but i think the 'event' property of the interface needs to have a `get function` & `set function` that are actually the `getEvent` and `setEvent` functions.

首先检查 rule.js 以及公开 rule.event 属性的类型定义。将重构后的 rule.ruleEvent 属性与 issue 中提到的 getEvent 和 setEvent 访问器进行比较，然后验证哪种形式允许通过类型直接访问属性。当类型与运行时行为一致，且直接访问按预期工作时，即表示完成。
