The additional thread is always started in-reserve to handle any non-worker mode requests. This block probably better fits into worker.md, somewhere here

Hi, first PR on that great project.
Having heavily played with configuration in the past weeks, I have noticed using Prometheus metrics frankenphp_total_threads and frankenphp_total_workers that the default value for num_threads changes whether the worker mode is enabled or not.
In other words, with the following restrictions on my compose stack for the FrankenPHP service:
In classic mode : 4 threads are created
In worker mode with "num : 4" : 5 threads are created.
So if you happen to explicity set num_threads, it has to be > that num to ensure the request thread is created, otherwise FKPHP won't start and will output this error message:
