CODITECT Retry Engine Unit Tests

Part of Track H.2.5: Inter-Agent Communication Infrastructure Tests for retry_engine.py - comprehensive coverage of all components

Test Categories: 1. Enum Tests (BackoffStrategy, JitterType, RetryDecision) 2. Exception Tests (RetryError, MaxRetriesExceeded, RetryTimeout) 3. RetryConfig Tests (validation, defaults, serialization) 4. RetryPolicy Tests (delay calculation, jitter, should_retry) 5. RetryEngine Tests (sync, async, metrics) 6. Decorator Tests (@retry) 7. Integration Tests (RetryWithCircuitBreaker) 8. Convenience Function Tests 9. Predefined Config Tests 10. Edge Case Tests

Run: pytest scripts/core/test_retry_engine.py -v
