测试仪器和 OpenTelemetry

🌐 Test instrumentation and OpenTelemetry

测试运行器通过 Node.js diagnostics_channel 模块发布测试执行事件，使其能够与像 OpenTelemetry 这样的可观测性工具集成，而无需对测试运行器本身进行修改。

🌐 The test runner publishes test execution events through the Node.js diagnostics_channel module, enabling integration with observability tools like OpenTelemetry without requiring changes to the test runner itself.
