Multi-Objective Option

When multi-objective routing is enabled (request field enableMultiObjective, or the multi_objective_routing_enabled merchant feature flag), a cost-aware post-step may re-rank the SR result and the response gains a multi_objective_info block. Details and examples: Multi-objective routing.
