Implement comprehensive data integrity and consistency tests
- Created 8 comprehensive test cases covering critical integrity scenarios:
* Concurrent constraint enforcement validation
* Referential integrity preservation between nodes and relationships
* Schema constraint consistency across multiple constraint types
* Concurrent node updates consistency with race condition handling
* Property deletion consistency under concurrent operations
* Graph statistics consistency tracking throughout operations
* Constraint modification consistency with existing data
* Data type consistency preservation across storage and retrieval
- Tests validate system behavior under concurrent access patterns
- Ensures data integrity is maintained during complex operations
- Validates constraint enforcement and schema consistency
- All tests pass, demonstrating robust data integrity implementation
- Provides comprehensive coverage of edge cases and failure scenarios
