feat: Add comprehensive S3 storage testing with mocks
CRITICAL: Ensures production reliability at scale - Add aws-sdk-client-mock for S3 testing without AWS resources - Create comprehensive test suite for ALL S3 operations - Test statistics persistence, recovery, and partitioning - Test rate limiting, throttling, and retry logic - Test concurrent operations from multiple services - Test data integrity with checksums - Test batch operations and performance optimizations - Simulate millions of records for scale testing - Ensure backward compatibility with legacy formats Also: Remove deprecated addSmart() method (functionality merged into add()) These tests are critical for production deployments where S3 is the primary storage backend for scaled systems handling millions of records.
