Assemble output patches from joined member rows.

load_patch resolves one member row to its source patch (residual selections included); merge_kwargs carries the merge behavior; plan_dim names the dimension whose range the plan narrowed, and trim_dims any others, which are the only ones a member needs trimming on. The plan resolver hands this the joined member frame for one output at a time.
