⚠️ 重要：该接口会真实发送消息到目标会话，不可用于测试或试探性调用。调用前必须确认消息内容和接收对象无误。

目标选择（三选一，必填）：
  --group              群聊 openconversation_id
  --user               单聊接收人 userId
  --open-dingtalk-id   单聊接收人 openDingTalkId

纯文本 / Markdown 消息（默认）：
  无需指定 --msg-type，直接传消息内容即可。推荐使用 --text flag 传递内容（尤其当内容含换行、引号等特殊字符时），也支持位置参数。可选 --title 作为消息标题。
  图文混排时，公网图片 URL 需要写成 Markdown 图片语法：![图片标题](https://example.com/image.png)，才会以内联图片展示。
  如果省略开头的 !，例如 [图片标题](https://example.com/image.png)，将按链接/URL 展示，不会渲染为图片。

返回值与后续操作：
  发送后会返回 openTaskId。如需编辑或撤回刚发送的消息，使用
  dws chat message query-send-status --open-task-id <openTaskId>
  获取 openMessageId 和 openConversationId，无需再按消息内容反查。

本地图片 / 文件消息：
  统一使用 --msg-type file --file-path <本地路径>。CLI 会完成上传并按 file 消息发送；
  .png/.jpg 也会显示为可下载的文件附件，不会生成 mediaId 或渲染成内联图片。

旧版内联图片消息：
  仅当上游已经提供有效 mediaId 时，使用 --msg-type image --media-id。
  当前 CLI 不提供本地文件到 mediaId 的上传能力。`,
		Example: `  dws chat message send --group <openconversation_id> "hello"
  dws chat message send --user <userId> "请查收"
  dws chat message send --open-dingtalk-id <openDingTalkId> "请查收"
  dws chat message send --group <openconversation_id> --title "周报提醒" "请大家本周五前提交周报"
  # 图文混排 Markdown：公网图片 URL 需要写成 ![图片标题](URL) 才会以内联图片展示
  dws chat message send --group <openconversation_id> --text $'这是图文说明\n\n![这个是展示图片标题](https://down.dingtalk.com/media/lQLPM5jiBEiBNjswMLAKd_CTzm8eowpEWPT_7-cA_48_48.png)'
  # 发送本地图片或文件（图片会作为可下载的 file 附件发送）
  dws chat message send --group <openconversation_id> --msg-type file --file-path ./screenshot.png
  dws chat message send --group <openconversation_id> --msg-type file --file-path ./report.pdf
  # 发送本地音频/视频（audio/video 是 file 的语义别名）
  dws chat message send --group <openconversation_id> --msg-type audio --file-path ./recording.mp3
  dws chat message send --group <openconversation_id> --msg-type video --file-path ./demo.mp4
  # 旧版内联图片：仅当上游已经持有有效 mediaId 时使用
