fix(pidpicker): eliminate defer-inside-goroutine-in-loop anti-patterns

Extract the per-pid goroutine body from scanAllThreadsFrom into a named
scanThreadsWorker function. This removes both defer statements from the
anonymous closure that was spawned inside a for loop: the semaphore
release is now an explicit <-sem call immediately after I/O completes,
and wg.Done() is called directly after scanThreadsWorker returns.
