fix: run brew commands on a serial queue, one at a time

Browse source 
runBrew dispatched onto the global concurrent queue, so overlapping
operations (refresh timer firing mid-upgrade, quick manual actions)
ran multiple brew processes at once — each able to summon its own sudo
password dialog, hence duplicate password windows. A private serial
queue makes every brew command wait for the previous one, so a second
dialog cannot appear while one is open. Log output no longer
interleaves either.
