[BUG]QQ channel无法正确根据bindings区分agent

[cysnb]

Quick Summary

Environment & Tools

• **PicoClaw Version:0.2.0 预编译版本
• **Go Version:
• **AI Model & Provider:DeepSeek
• **Operating System:Docker
• Channels: QQ

📸 Steps to Reproduce

1. 修改配置

"session": {
    "dm_scope": "per-account-channel-peer"
  },
  "agents": {
    "defaults": {
      "workspace": "~/.picoclaw/workspace",
      "restrict_to_workspace": true,
      "provider": "",
      "model_name": "deepseek-chat",
      "max_tokens": 8192,
      "max_tool_iterations": 50
    },
    "list": [
      {
        "id": "z",
        "workspace": "~/.picoclaw/z",
        "model": "deepseek-chat"
      },
      {
        "id": "x",
        "workspace": "~/.picoclaw/x",
        "model": "deepseek-chat"
      }
    ]
  },
  "bindings": [
    {
      "agent_id": "z",
      "match": {
        "channel": "qq",
        "account_id": "5694B*******"
      }
    },
    {
      "agent_id": "x",
      "match": {
        "channel": "qq",
        "account_id": "7750283*********"
      }
    }
  ],

2. 启动docker容器
3. 将2个不同的QQ均添加该机器人，这两个QQ号码的后端接口调用时的id分别是 5694B******* 和 7750283*********

4. ❌ Actual Behavior

两个QQ被路由到同一个agent上了。日志如下：

✅ Expected Behavior

应该按照bindings配置，使用不同的agent才对。

💬 Additional Context

[cysnb]

感觉问题可能出在 https://github.com/sipeed/picoclaw/blob/v0.2.0/pkg/channels/qq/qq.go 的第 171 行：

// 转发到消息总线
		metadata := map[string]string{}

是否应该这样：

metadata := map[string]string{
			"account_id": data.*********,
		}
