* chore: only retry when retry-able * chore: revert dbg change * refactor: per review * fix: check for available frontend first * docs: more explain&longer timeout&feat: more retry at every level&try send select 1 * fix: use `sql` method for "SELECT 1" * fix: also put recover flows in spawned task and a dead loop * test: update transient error in flow rebuild test * chore: sleep after sqlness sleep * chore: add a warning * chore: wait even more time after reboot
