Run in-process on an app that already published its pool, queue:clear failed
with "backpack: duplicate provider for *sql.DB". It now goes through
withAppDB; the CLI path is unchanged.
- queue:work and schedule:run print their summary block only on a
terminal; off one (the test's buffer) they log 'startup summary' and
'shutdown report' records of component queue/schedule, so the tests
still asserted the pre-19.8 Info lines
- captureDiary bootstraps diary on a buffer; TestQueueWork and
TestScheduleRunForeground wait for the startup summary record and
check the shutdown report record
