### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: Invalid column internals, such as a nullable column whose
nested column size differs from its null map size, may only fail later when a
downstream operator reads nested data. This change runs column sanity checks at
pipeline operator output boundaries, including projection outputs, so malformed
columns are reported closer to their producer. It also keeps targeted nested
loop join lazy materialization sanity checks at the source-copy points that
exposed the issue.
