Tool results now use content blocks and can include both text and images. All providers (Anthropic, Google, OpenAI Completions, OpenAI Responses) correctly pass images from tool results to LLMs. - Update ToolResultMessage type to use content blocks - Add placeholder text for image-only tool results in Google/Anthropic - OpenAI providers send tool result + follow-up user message with images - Fix Anthropic JSON parsing for empty tool arguments - Add comprehensive tests for image-only and text+image tool results - Update README with tool result content blocks API
