"""wechatauto v1.0.9 转发语音演示 —— 从本地媒体库提取 SILK 并作为文件发送

微信不支持右键直接转发语音消息（无转发入口），本项目实现为：
    「本地媒体库提取 SILK 音频文件 → 以文件消息发送给目标联系人」。

链路：
    1. 打开会话，定位最近一条语音消息（mmui::ChatVoiceItemView / DB 语音）；
    2. MediaDownloader.download_voice 从 media_0.db 提取 voice_data 落盘 .silk；
    3. WeChatGUI.send_file 以文件消息发送给目标。

用法：
    python demo_forward_voice.py                      # 小哲→文件传输助手（安全演示）
    python demo_forward_voice.py --target 豆芽        # 指定转发目标
    python demo_forward_voice.py --who 群名 --target 某人
