Add support for AWS Bedrock as an LLM provider using the Converse API. The implementation is behind a build tag (-tags bedrock) to keep the default binary size small. Features: - AWS SDK v2 with automatic credential chain (env vars, profiles, IAM roles) - Converse API for unified access to Claude, Llama, Mistral models - Tool/function calling support with proper document handling - Image support with base64 decoding and size limits - Request timeout configuration - Region validation and endpoint resolution for all AWS partitions Usage: go build -tags bedrock model: bedrock/us.anthropic.claude-sonnet-4-20250514-v1:0 api_base: us-east-1 (or full endpoint URL)
