Force a full rebuild after this many consecutive incremental (Incremental/DirtyGroupRecompute)
refreshes. The incremental delete-detection guard only trips on a NET source row-count drop; a
delete BALANCED by an insert in the same window (net-zero change) leaves the deleted row's group
stale until another change touches it. This periodic full rebuild bounds that drift to at most
this many refresh cycles without requiring the author to schedule a manual FullRebuild.
