**feat(models): enhance loader reliability and compatibility**
- **Compatibility Enhancements**: - Added support to detect and inject missing `"format"` field in `model.json` files for TensorFlow.js compatibility. - Modified model loading logic to handle both `tfjs-graph-model` and `tfjs-layers-model` formats. - **New Features**: - Introduced additional fallback paths for locating models to increase reliability in varying environments. - Added support for mock implementations of the Universal Sentence Encoder in test environments. - **Bug Fixes**: - Fixed module loading resolution in `FileSystemStorage` with improved initialization and error handling for Node.js environments. - Resolved issues with test assertions to improve validation logic in core tests. **Purpose**: Improve model loading reliability, expand compatibility with TensorFlow.js models, and enhance test environment support.
