/claim #1659

Summary

• add SQL NULL semantics for static IN / NOT IN lists and mark the expression output nullable
• cover static IN list streaming semantics for non-matching inserts, false-to-true updates, true-to-true updates, true-to-false updates, and deletes
• lower expr IN (SELECT one_column ...) filters into an inner join against a deduplicated derived subquery, reusing the existing join/set processors instead of adding a parallel membership engine
• preserve additional AND predicates and reject invalid multi-column IN subqueries
• add scripted streaming coverage for matching rows, late-arriving membership rows, unqualified outer identifiers, retained predicates, duplicate inner rows, and duplicate-membership deletion
• add sqllogictest fixtures for static IN, IN (SELECT ...), retained predicates, duplicate inner rows, membership deletes, outer-row updates, and late membership inserts

Issue coverage

This covers literal IN lists in selection predicates, including the update/delete behavior described in the issue, and streaming IN (SELECT ...) subqueries with membership semantics.

The subquery path rewrites into Dozer's existing streaming inner join plus a deduplicated derived subquery. That keeps runtime behavior aligned with the established join/product pipeline while preventing duplicate right-side rows from duplicating left-side output.
