📝 Description

修复飞书（Feishu/Lark）话题群中机器人回复不进入话题的问题。

在飞书话题群（topic_group）中，当用户发送一条消息创建一个话题后，机器人回复时没有在该话题下回复，而是每条回复都创建一个新的话题。本 PR 修复了此问题，使机器人能够在正确的话题下回复。

📚 Technical Context (Skip for Docs)

• Reference URL:
  • 飞书消息 ID 说明: https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/im-v1/message/intro#ac79c1c2
  • 飞书 ReplyMessage API: https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/im-v1/message/reply
• Reasoning:
  飞书的消息事件包含 ThreadId 字段表示消息所属的话题。在话题群中回复消息时，需要使用 ReplyMessage API 并设置 ReplyInThread=true 参数，才能在同一话题下回复。原代码未处理此字段和参数，导致回复创建了新话题。

🧪 Test Environment

Based on my observation, this feature only requires modifications to the Feishu channel, and should not introduce coupling specific to a particular channel in the public domain
