Add retry logic to all HTTP methods: - doRetry() core loop with configurable max retries - Exponential backoff with 0.5-1.5x jitter - Retry-After header support (seconds and HTTP-date) - Retry on 429 and 5xx; no retry on 4xx client errors - Context cancellation respected during retry delays - Multipart uploads also retry via doRetry() - 9 new tests: 429/500 recovery, exhaustion, no-retry-on-400, backoff math
