Error Handling And Retry Logic With Provider Specific Fallbacks

Unique: Implements provider-aware retry logic that distinguishes between retryable (429, 503) and fatal (401, 400) errors, with exponential backoff and configurable max retries. Error context (provider, request, failure reason) is logged for debugging and monitoring.

vs others: More sophisticated than naive retry-all approaches because it classifies errors and avoids wasting retries on unrecoverable failures; more flexible than fixed-delay retries because exponential backoff adapts to varying failure durations.
