## Title

    Proposed fix: [Amazon Bedrock Converse + Claude] 400 'This model doesn't support the s3Uri field. Remove s3Uri and try again.' — S3 image sources not accepted for Claude

## Body

    Recommended action: Download the S3 object and send image bytes (<=3.75 MB per image, <=8000x8000 px, up to 20 images) for Claude; keep S3 URIs for models that support them.
    
    Option: Inline image bytes for Claude [evidence: documented_workaround]
    Steps:
    1. Fetch the S3 object with GetObject.
    2. Send it as image.source.bytes.
    Expected: Request accepted.
