Merge claude/2

'Checking for improvements… this usually takes a minute.' implied an active
scan finishing imminently. The scan is periodic and runs in the background
(CFG_UPDATER_SCAN_INTERVAL, default 30m), so reword to reflect that. Kept the
cadence generic since the interval is admin-configurable and not exposed here.
