"""
向开发群 webhook 发送一条长文本 + 若干本地 PNG（先上传飞书再发 image_key）。
依赖：与 send_chapter_poster_to_feishu.py 相同，需 scripts/.env.feishu 内 FEISHU_APP_ID / FEISHU_APP_SECRET。

用法:
  python3 send_feishu_text_and_images.py --text-file recap.txt \\
    --images a.png b.png
  python3 send_feishu_text_and_images.py -t "单行文本" --images x.png
