v1.3.3

- Fixed a rare failure mode where a sync running right after Kodi starts, a library scan/clean finishes, or a temporarily unreadable video library could be misread as "everything was removed" and push that as a mass removal to MDBList (or, in the reverse direction, unwatch a batch of items locally). Removals are now only ever applied on a deliberate sync (the 24-hour background sync or manual "Sync now"), and a suspiciously empty or oversized removal batch is held and retried on the next sync instead of applied.
