Garry Tan	02925cfc7a	feat: wire costs[] from modelUsage into eval results ... Extract per-model token usage from resultLine.modelUsage (including cache tokens and exact API cost), flow CostEntry[] through EvalCollector, aggregate in finalize(). Extend CostEntry with cache_read_input_tokens, cache_creation_input_tokens, cost_usd. computeCosts() prefers exact cost_usd over MODEL_PRICING when available (~4x more accurate with prompt caching).
