Images sent by users were silently dropped when the model supported
vision: routeAttachmentsByCapability classified them as "Native", but
extractFileRefPaths only collected "Fallback" (tool_file_ref) paths,
so the image data URL was computed and then discarded — the model saw
neither the image nor its container path.
- Add InlineImages field to RunConfig to carry native image data
- Replace extractFileRefPaths with extractAttachmentPaths that
collects paths from both Native (FallbackPath) and Fallback
attachments so the YAML header always lists every attachment
- Add extractNativeImageParts to extract inline image data URLs
- Pass InlineImages as sdk.ImagePart in prepareRunConfig so the
LLM receives the actual image content alongside the text query
