Bug Description

When receiving a group message in Feishu, the session's groupId field is incorrectly set to the sender's open_id instead of the group chat ID.

This causes the embedded agent to be unable to reply to group messages because the tool policy drops the groupId (due to mismatch between caller-provided groupId and session-derived group context).

Steps to Reproduce

1. Add zhaolusi bot to a Feishu group
2. Have a user @mention the bot in the group
3. Bot receives the message (confirmed in logs) but does not reply

Session Data

  "groupId": "ou_8e30b912972e84bbc307b54700a9dbd5",  // WRONG: sender's open_id
  "origin": {
    "from": "feishu:ou_8e30b912972e84bbc307b54700a9dbd5",
    "to": "chat:oc_f8380977f61fa0ec25bbbdebdeb90ff5"  // CORRECT group chat ID in origin.to
  }
}
