invalidateRecent(days) drops the cached pages holding anything diigo
updated within the last N days (on the cache's injected clock), and
every page before them, so the next read or fill refetches them; item
rows stay. Exposed on the fill capability (private and public) and on
the webkey page as "invalidate the last N days" per cache.
A user-requested refetch, not a change in what stored state means.
