Queue behind stronger lockers; bump gatelock to v0.7.1

Diet_guard was one of the two lockers missing gatelock's
wait_for_turn fix -- confirmed live on 2026-08-21, it held the global
grab for ~3 minutes against a newly-arriving, higher-ranked
screen_locker, which just retried and logged instead of making
progress. Now queues behind any stronger claim before arming.
