Integrate tokio-console

[teor2345]

Scheduling

This ticket is only required if we've fixed all the known hang bugs in Zebra, and Zebra still has frequent hangs.

Is your feature request related to a problem? Please describe.

It's hard to see what tokio is doing inside Zebra.

another cool thing the console does now is its ⚠️warnings system. this is like a linter, but for your program’s runtime behavior. by monitoring the tasks in the application, we can detect behavior patterns that might indicate bugs or performance issues.

I've marked this as a medium priority, because we still have hang and performance bugs in Zebra that are hard to diagnose and fix.

We don't need to do this unless there are some performance or hang issues we need to fix.
