Add S3 cache download validation and retry logic
- Add empty file validation (0 bytes) and minimum size checks (512 bytes) for tar archives
- Implement download completeness validation (bytes downloaded = expected)
- Add retry logic with exponential backoff for validation failures (3 attempts: 1s/2s/4s delays)
- Create DownloadValidationError class for specific validation failures
- Add comprehensive test coverage for validation scenarios
- Maintain graceful degradation - validation failures log warnings but don't fail workflows
