回调通知格式​

生成完成后，系统向 callbackUrl POST 以下数据：

成功时：

{
  "taskNo": "a1b2c3d4...",
  "status": "success",
  "model": "seedance-1.5-pro",
  "timestamp": 1234567890,
  "data": {
    "task_id": "6928de47-2e53-4ee6-901b-be05a8bf7669",
    "status": "SUCCESS",
    "request_id": "7d8d7f71a7314779b6947eed659085fa",
    "result": [
      "https://cdn.example.com/result_1.mp4"
    ],
    "error_info": "",
    "traceback": ""
  },
  "usage": { "totalPoints": 10 },
  "sign": "sha256hex..."
}

失败时：

{
  "taskNo": "a1b2c3d4...",

  "model": "seedance-1.5-pro",
  "timestamp": 1234567890,
  "error": "错误信息",

签名验证：sign = SHA256(taskNo + timestamp + apiKey)
