Pushed the fix for the negated-extract pruning blocker - a NOT over an
extract now collapses to AlwaysTrue (and hasExtract propagates through AND/OR,
so nested NOTs are covered), so negation can't fold the pruning filter into a
lossy AlwaysFalse. Added a regression test as well -
NOT(Eq(Extract("payload","$.a",Int64),1)) with a payload.a=2 row, asserting it
survives - plus coverage for the required-variant-column bind, the
tz/zoneless cast rejection, and missing/wrong-type residual columns. Also
strips extracts before TranslateColumnNames so the incremental-scan path no
longer hits ErrNotImplemented.
