-- Small key-value table for daemon state that needs to survive restarts.
--
-- Used so far only by the cron scheduler (`last_metadata_tick_at`) so it can
-- detect that the most recent slot was missed (e.g. the backend was down at
-- midnight) and fire immediately on startup before resuming the regular
-- schedule. JSONB on the value column lets future keys carry richer payloads
-- without another migration.
