* Fix profiler shutdown when isolate is terminated When an isolate is terminated abruptly (eg. by Worker.terminate()), the profiler is not stopped and not removed from the isolate->profiler map. This can lead to a crash. This commit adds a cleanup hook with `node::AddEnvironmentCleanupHook` that is called when the isolate is destroyed. The cleanup hook stops the profiler and removes it from the profiler map.

⚪ Code Quality Violation
Unexpected unnamed function. (...read more)
It is easier to debug your application code when you avoid anonymous functions so that the stack trace can show you meaningful error messages. This rule enforces all your function to be consistently declared with a name.
