Pull request overview
Enables native conversion of Spark SMJ/SHJ inner joins that have an additional residual (non-equi) predicate by keeping the native join keyed-only and evaluating the residual predicate via a native Filter above the join.
Changes:
- Allow native SMJ/SHJ conversion for
InnerLikejoins with a residualcondition, applying it as a native filter above the join. - Add query tests covering SMJ/SHJ inner residual conditions (including force-SHJ mode) and a SparkConf test helper.
- Update TPCDS plan-stability golden files to reflect the new
NativeFilter/NativeProjectshapes.

Which issue does this PR close?
Closes #2193
Rationale for this change
Auron currently only converts SMJ/SHJ joins when the join condition is empty. As a result, inner joins that contain both equi-join keys and a residual predicate fall back to Spark even though the equi-join part is already native-compatible.
The native join plan only models equi-join keys today, so this change keeps the native join focused on the equi-join portion and evaluates the residual predicate with a native filter above the join output.
What changes are included in this PR?
Are there any user-facing changes?
Yes. Inner joins with equi-join keys plus a residual predicate can now remain on the native SMJ/SHJ path instead of falling back entirely to Spark.
How was this patch tested?
CI.
