[Testing] [Feature]: Assert on events for examples

Migration from https://github.com/aws/aws-durable-execution-sdk-python-testing/issues/181

---

### What would you like?

Currently we do manually asserts in integration tests.

We should be able to:

1. Generate events from local runner
2. Assert current events with the events in the json file

### Possible Implementation

_No response_

### Is this a breaking change?

No

### Does this require an RFC?

No

### Additional Context

_No response_

首先跟踪当前手动断言事件的集成测试，以及生成这些事件的本地运行器。定义将当前事件与 JSON 文件中的事件进行比较时的预期行为，然后验证示例使用了新的断言并且仍然通过。
