Fixes #2350 (from #2118). The Anthropic client logged `cache_creation_input_tokens` and `cache_read_input_tokens` and then returned only `input_tokens` and `output_tokens`, so every cached Patrol run reached the usage ledger, the cost preview, the budget check and the weekly digest with its cache buckets missing. #2350 reproduced the loss on both the `Chat` and `ChatStream` paths. Both response paths now carry the two buckets as fields disjoint from `InputTokens` (streaming assigns them from `message_start` and the final cumulative `message_delta` rather than summing). The agentic loops, Patrol responses and run records sum them beside the ordinary totals, the usage ledger and its persisted copies keep them, and `cost.EstimateUsageUSD` prices each bucket at Anthropic's published cache rates (5-minute write 1.25x, read 0.1x of the input rate), falling back to the input rate for providers without a known cache price. Spend summaries, the digest spend, the cost projection medians and the usage export expose the buckets and price them the same way. `InputTokens` keeps its meaning everywhere, so the telemetry token buckets are unchanged. Proof: `anthropic_test.go` (both response paths keep the buckets; the final delta does not double them), `pricing_anthropic_test.go`, `store_test.go`, `patrol_digest_test.go`, `patrol_cost_projection_test.go`, `cost_persistence_test.go`, and `ai_handlers_more_test.go` for the export in both formats. This repairs lost accounting data; it is not a measured provider bill or a claim of savings across six-hourly runs.
