Integrate an opt-in OpenCV visualizer into the demo runtime so operators can monitor tracking, segmentation, and inference confidence in real time without changing the default non-visual execution path.
Add the full demo runtime stack for single-person scoliosis inference, including input adapters, silhouette preprocessing, temporal windowing, ScoNet wrapper, result publishing, and click-based CLI orchestration. This commit captures the executable pipeline behavior independently from tests and planning artifacts for clearer review and rollback.
