/**
 * Streaming run-fn for the `["text.generation"]` capability. Used by both
 * {@link TextGenerationTask} (prompt-only input) and {@link AiChatTask}
 * (full conversation history). Yields `text-delta` events on the `text` port
 * and a final empty `finish` event per the streaming convention (consumer
 * accumulates).
 *
 * Discriminates on `Array.isArray(input.messages) && input.messages.length > 0`
 * to choose the chat vs. prompt path — safe because AiChatTask always provides
 * `messages` and TextGenerationTask never does.
