The changeset claims support was added across all providers including OpenRouter, but the PR description explicitly states OpenRouter support wasn't added. Could we update this to accurately reflect what was implemented?

- Updated anthropic.ts provider to handle prompt caching for the new model
- Pricing: $15/M input tokens, $75/M output tokens, $18.75/M cache writes, $1.5/M cache reads

Is this intentional? I noticed that claude-opus-4@20250514 (line 190) doesn't have supportsReasoningBudget: true, but the new claude-opus-4-1@20250805 does. Should we add it to the 4.0 model for consistency, or is there a specific reason for this difference?
