AI Summarization Backfill is stuck, keeps regenerating the same topic

Again, backfilling is not going to work well yet for others, because of the created_at issue.

Yeah I agree, we need to look at updated_at or last_posted_at which is slightly less radical.

At the end of the day if we are backfilling we should base it on content change.
