- Fix JoinScan pushdown with outer-only `ORDER BY` pathkeys.
- Fix `pdb.score()` with `SELECT` subquery in `WHERE` clause.
- Handle `IN (SELECT ...) OR IS NULL` via LeftMark JoinScan.
- Fix score filter for joins and cases without other quals.
- Handle pruned columns in nested semi/anti join keys.
- Handle aliased indexed expressions in search resolution and top-k order by.
- Lower x86_64 target-cpu from x86-64-v3 to x86-64-v2 for broader hardware compatibility.
- Prevent DSM buffer overflow in PG18 parallel index scans.
- Fix `PlaceHolderVar found where not expected` error.
- Restore `pdb.agg(jsonb)` if accidentally removed by an upgrade script.
