test: 添加单账号 503 退避重试机制的单元测试
覆盖 Service 层和 Handler 层的所有新增逻辑： - isSingleAccountRetry context 标记检查 - handleSmartRetry 中 503 + SingleAccountRetry 分支 - handleSingleAccountRetryInPlace 原地重试逻辑 - antigravityRetryLoop 预检查跳过限流 - sleepAntigravitySingleAccountBackoff 固定延迟退避 - 端到端集成场景验证 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
