[Bedrock] Update Claude model catalog metadata #302

Which API Provider are you using?

AWS Bedrock

Which Model are you using?

Claude 4.x on Amazon Bedrock

What happened?

The Bedrock model catalog needs current Claude metadata so Zoo Code can expose the right max output caps, context windows, prompt-cache TTLs, and Claude Opus 4.7 entry.

Steps to reproduce

1. Review the Bedrock catalog changes proposed in [ENHANCEMENT] Improve Amazon Bedrock support #125.
2. Keep the implementation scoped to packages/types model metadata and directly related tests.
3. Verify the updated metadata with package-local unit tests.

Acceptance criteria:

• Bedrock Claude 4.x entries expose the intended maxTokens values.
• Claude Opus 4.7 is available as a Bedrock model entry.
• 1M-capable models expose that capability through metadata.
• promptCacheTtl is represented for supported Bedrock prompt-cache models.
• Package-local tests cover the changed catalog entries.
