shouldAutoCheckYtdlp compared (now - lastCheck) >= interval; a backward system-
clock correction leaves lastCheck in the future so the difference is negative and
the daily check never comes due again. Treat a future lastCheck as skewed and run
the check. The renderer scheduled-item promoter is inherently fire-once (promotion
flips the item out of 'saved'), so it can't double-fire on a backward jump — a
forward jump firing early is documented and accepted as minor.
Unit-tested. typecheck + 263 tests + eslint + prettier green.
