NESTED_LOOP_JOIN_INNER_U32_1KEY_PAIRS

Nested-loop inner join (emit-pairs design). Reads the single key column from each side; emits matched (left_idx, right_idx) pairs as two parallel u32 arrays. Payload columns are materialized after the kernel via gather_buffer_by_indices in the provider fn.

SORT_MERGE_JOIN_INNER_U32_1KEY_PAIRS

Sort-merge inner join (emit-pairs design, caller-asserted pre-sorted inputs). Reads the single key column from each side, performs per-thread binary search on the right side to find matched-key runs, emits (left_idx, right_idx) pairs as two parallel u32 arrays. Payload columns materialize after the kernel via gather_buffer_by_indices.
