> For joins, we create runtime filters that are sent from the build side to the probe side to do some early filtering of results of a scan. With shared CTEs, the consumers may not receive the same runtime filters, so we can't forward them all the way to the scans, but we should be able to apply them to the CTE consumer results. Implement support for connecting runtime filters to CTE consumers.
