feat: Complete comprehensive test_tools implementation with advanced features

- Implement behavioral equivalence verification framework ensuring re-exported utilities maintain identical behavior to originals
- Add sophisticated dependency configuration system with local/published path support, features, and dev dependencies for enhanced smoke testing
- Complete enhanced smoke testing with automatic cleanup, verification mechanisms, and conditional execution based on environment detection
- Implement comprehensive API stability facade with namespace isolation and root-level utility re-exports for seamless user experience
- Add extensive test coverage across all major functionality areas including standalone build mode verification
- Complete tasks 009, 011-012, 018, 023-024 marking major milestones in mod_interface aggregation, API stability, and cleanup functionality
