PinThreadToCPU left the goroutine locked to its OS thread even when
sched_setaffinity failed. The lock only exists to make the affinity
stick; without it the kernel migrates the thread anyway, so a failed pin
kept a dedicated thread for zero benefit. Unwind on the error path.

* upgrade to yaml.v3
The main nice fix here is that maps unmarshal into `map[string]any`
instead of `map[any]any`, so it cleans things up a bit.
* add config.AsBool
Since yaml.v3 doesn't automatically convert yes to bool now, for
backwards compat
* use type aliases for m
* more cleanup
* more cleanup
* more cleanup
* go mod cleanup
