Abstract Formatter interface for rendering components to strings. A Formatter converts Component and CBlock objects into the text strings fed to language model prompts. The single abstract method print encapsulates this rendering contract; concrete subclasses such as ChatFormatter and TemplateFormatter extend it with chat-message and Jinja2-template rendering respectively.
