fix(cmd-k): Decouple debounce timer from async result count changes

filteredActionCount in the debounce effect deps caused the 500ms timer
to restart when async results arrived (e.g. DSN lookup), delaying or
losing the searched event. Now sync the count to a ref and read it
inside the timeout callback so the timer only resets on query changes.
