// Stub AI strategy — reserves extension point for a future ML model (ONNX / HTTP).
//
// Current behaviour: always returns an empty schedule with a human-readable
// fallback message, and reports itself as unavailable.
//
// Future extension hooks:
//   - setModelPath(path)  → load ONNX model
//   - setRemoteEndpoint(url, apiKey)  → delegate to HTTP inference service
//   - When a model is loaded, override isAvailable() to return true and
//     implement computeSchedule() to call the model.
