### Description

This is a followup to #85926.

As part of the ingest processing pipeline, we call `CollectionUtils.ensureNoSelfReferences(...)` to ensure that a script processor didn't accidentally introduce a circular object. However, this check is only necessary if we know there was the potential for a circular option, which can only happen with either a custom processor (a plugin where we have no control), or a script processor. We should be able to only call this sanity check if we know we need it, rather than for every document.
