Introduce a 10‑second timeout for SMD token refresh operations to prevent potential deadlocks when the OIDC token endpoint is slow or unresponsive. A new constant defaultRefreshTimeout is defined and used with context.WithTimeout in both RefreshToken and refreshTokenIfCurrent. A refreshLock mutex is added to serialize concurrent refresh attempts, ensuring only one refresh request proceeds at a time. Additionally, a benchmark BenchmarkRefreshToken (in smdclient_benchmark_test.go) measures the latency of the refresh path. Comprehensive tests have been added to verify correct behavior under concurrent requests. These changes improve robustness of the SMD client during token expiration handling.
