[Bug] 主动回复遗漏图片信息传递

[Dominic485649]

What happened / 发生了什么

群聊未 @ 的消息走了内置“主动回复”路径，它只传了 event.message_str，而纯图片消息的文本为空，也没有把 image_urls 传给 LLM，所以主代理根本看不到图片

修复方式：
py312\Lib\site-packages\astrbot\builtin_stars\astrbot\main.py

178行起改动为

                    prompt = event.message_str
                    image_urls = []
                    image_attachment_parts = []
                    for comp in event.message_obj.message:
                        if isinstance(comp, Image):
                            try:
                                image_path = await comp.convert_to_file_path()
                                image_urls.append(image_path)
                                image_attachment_parts.append(
                                    f"[Image Attachment: path {image_path}]",
                                )
                            except BaseException as e:
                                logger.error(f"主动回复处理图片失败: {e}")

                    if image_attachment_parts:
                        prompt_parts = image_attachment_parts.copy()
                        if prompt:
                            prompt_parts.append(prompt)
                        prompt = "\n".join(prompt_parts)

                    if not prompt and image_urls:
                        prompt = "<attachment>"

                    if not conv:
                        logger.error("未找到对话，无法主动回复")
                        return
                    yield event.request_llm(
                        prompt=prompt,
                        session_id=event.session_id,
                        image_urls=image_urls,
                        conversation=conv,
                    )

Reproduce / 如何复现？

启动主动回复，并且概率设置位100%，传递时候会遗漏图片，无法触发下一步操作（例如子代理等）

I can take this. The active-reply path currently forwards only event.message_str to request_llm(), so image-only messages arrive as an empty prompt and the image URLs are never attached. I'll prepare a small patch that extracts Image components in that path, passes them as image_urls, and keeps a placeholder prompt for image-only messages.
