   cc @cloud-fan — could you take a look when you get a chance? This is a 
correctness fix for `PushProjectionThroughLimitAndOffset`: subquery expressions 
pass the `deterministic` guard but get rewritten into joins later, which breaks 
sort order when placed below Limit/Offset. One-line guard change + unit tests + 
end-to-end SQL tests.
