   # Which issue does this PR close?
   
   Closes #2539 
   
   # Rationale for this change
   Native broadcast hash joins currently support residual conditions only for inner joins. Other join types, such as outer, semi, anti, and existence joins, fall back to Spark when the join includes an additional condition such as `l.k = r.k AND l.v < r.v`.
   These conditions must participate in determining whether rows match. Applying a filter after the join cannot preserve the required semantics for these join types.
   
   # What changes are included in this PR?
   
   - Extend native broadcast hash joins to evaluate residual conditions for supported outer, semi, anti, and existence joins using the shared join-condition evaluator.
   - Update match tracking only for candidate pairs that satisfy the condition, preserving unmatched rows and existence results.
   - Bound candidate batches when processing duplicate keys and gather only the columns required by the condition.
   - Preserve output projections and row counts, including when execution falls back to native sort-merge join.
   - Add Rust and Spark regression tests covering join types, build sides, nulls, projections, spill behavior, and the existing configuration switch.
   
   # Are there any user-facing changes?
   No.
   
   # How was this patch tested?
   UTs.
