Why
Prerequisite for workload DAG migration in #512; stacked on #513. The old pin diverged from Planner main, which now has BinaryOp and typed summary update semantics.
Before this PR
The backend used cb50219 and old SummaryAgg column/Concat shapes, preventing adoption of merged Planner workload and arithmetic capabilities.
After this PR
Pin merged Planner d0701dd, preserve discriminator metadata, adapt summary input bindings, and use canonical promql workload JSON. Unsupported binary execution remains explicit fallback until its execution slice lands; this PR does not claim arithmetic serving is complete.
Validation
Existing TopK PR #505 overlaps the pin and summary-input transition; reconcile its remaining weighting/evidence work instead of merging its old pin over this one.
