leonai 948283187c feat(kiro): 添加认证错误自动标记不健康及凭证切换重试机制,解决401 和403的问题
1. Kiro API 新增 401/403 错误处理逻辑,401 尝试刷新 token 后重试,403 直接标记凭证不健康
2. 新增 _markCredentialUnhealthy 辅助方法,统一处理凭证健康状态标记
3. ProviderPoolManager 新增 markProviderUnhealthyImmediately 方法,用于认证错误立即标记
4. handleStreamRequest/handleUnaryRequest 支持重试上下文,认证失败后自动切换健康凭证重试
5. provider-api 健康检查增加认证错误识别,触发立即标记不健康逻辑
