Review completed. No issues found.

The changes correctly remove legacy models from the AWS Bedrock provider:

• Claude 2 series models (no longer available in Bedrock)
• Amazon Titan embedding models (not appropriate for model selection)

Test updates appropriately use Claude 3 Sonnet with correct pricing assertions.
