feat(sql): support streaming IN / NOT IN subquery and mixed-type IN list evaluation

[open5588]

/claim #1659

Summary

Extends Dozer streaming SQL IN / NOT IN support for both static value lists and dynamic IN (SELECT ...) subqueries (#1659).

Changes

1. Static IN (...) / NOT IN (...) list evaluation (dozer-sql/expression/src/in_list.rs):
   • Evaluates the left-hand expression once per record and uses evaluate_eq for consistent SQL equality and numeric type coercion across IN list items.
2. Dynamic IN (SELECT ...) / NOT IN (SELECT ...) streaming processor (dozer-sql/src/selection/in_subquery.rs, dozer-sql/src/builder/mod.rs):
   • Adds InSubqueryProcessorFactory and InSubqueryProcessor, a two-port streaming processor that maintains outer-table records and reference-counted inner-subquery keys.
   • Emits downstream Insert / Delete / Update transitions when either the outer table or inner subquery stream receives Insert, Delete, Update, or BatchInsert operations.
   • Supports IN (SELECT ...) and NOT IN (SELECT ...) both standalone and combined with AND predicates in WHERE clauses.
3. Tests:
   • Unit and DAG builder tests covering InSubqueryProcessor streaming transitions (Insert, Delete, Update, duplicate subquery keys, NOT IN visibility inversion), pipeline construction, and mixed-type IN list evaluation.
