MiniMax Director — Prompt

Show the compiled prompt, updating as the timeline is edited. `PreviewAny` would display the same string, but only after a run: it fills from execution results, so while you are writing the timeline the box sits empty -- which is exactly when you want to read what the model is being told. This node exists so the editor has somewhere to put its own answer. Wire the director's `prompt` output to `source` and the web extension paints it here on every edit pause, compiled by the same code the graph would run. Executing the graph fills it the ordinary way, so the node is honest with the extension missing.
