A complete AWS SDK v3 integration for Bedrock Runtime has been added, including:
- Bedrock Runtime client with full middleware stack
- AWS Signature Version 4 (SigV4) request signing
- OAuth2 credential provider for AWS login flows
- ECS/EKS container credentials support
- Assume Role with MFA support
- 30+ Bedrock API command definitions (guardrails, inference profiles, model management)
- AWS STS client for credential operations
- EventStream marshalling for real-time bidirectional communication
This replaces the previous Bedrock integration approach with a more complete, standards-compliant AWS SDK implementation.
