Measured on the live library: 6 stray files at the root of _unsorted made the
whole collection dump ONE item of 5,693 tracks, with 542 real books folded into
it; no scan subdivides an existing item. Also pinned: the items endpoint hands
back ceil(total/limit)*limit rows because an out-of-range offset repeats the
tail (that is where "exactly 1,500" and "exactly 4,000" came from), and
DELETE /api/items/:id?hard=1 runs fs.remove() on the item's folder - pointed at
a covering item that is the whole subtree, so un-swallowing is a DB-only delete
after the stray root files are filed.
