UsageAccumulator class final

Mutable accumulator summing Usage across turns of an agent run.

Token fields are summed directly; Usage.reasoning and Usage.cacheWrite1h are optional per provider, so the accumulated total reports them as null until at least one added usage reported them. Costs are summed field by field.
