Message:
add CanStream to LLMFunc, add tool_result fields to ContentBlock Phase 1 of the streaming integration plan. CanStream is a boolean capability on LLMFunc that marks which providers support streaming responses. Also adds ToolUseID, Content, and Output fields to ContentBlock to properly model tool_result content blocks.
