…oin pushdown (#61635) Push PreferPushDownProject expressions to the matching join child as aliases and replace them with slots in filter predicates. This keeps OR predicates above join while exposing nested-field access below join for storage-level pruning acceleration. Plan tree demo: Before: ``` LogicalFilter((match_any(info['context'], 'abc') OR r.k2 > 60)) LogicalJoin(INNER) left: LogicalOlapScan(student) right: LogicalOlapScan(score) ``` After: ``` LogicalFilter((slot#x OR r.k2 > 60)) LogicalJoin(INNER) left: LogicalProject(student.*, match_any(info['context'], 'abc') AS slot#x) LogicalOlapScan(student) right: LogicalOlapScan(score) ```
