    "query": "Help me develop a system to predict customer churn using the Telco Customer Churn dataset, potentially being downloaded from [this link](https://huggingface.co/datasets/scikit-learn/churn-prediction). Load the dataset in `src/data_loader.py`. The project should include feature engineering, such as feature selection and scaling, and handle imbalanced data using oversampling or undersampling techniques implemented in `src/data_loader.py`. The exact details of this are left for you to decide. Implement a Logistic Regression model in `src/model.py` and perform cross-validation while training the model in `src/train.py`. Finally, print and save the classification report (including precision, recall, and F1-score) to `results/metrics/classification_report.txt`, and save a ROC curve to `results/figures/roc_curve.png`. Ensure the dataset loads smoothly with appropriate error handling. The feature engineering should thoroughly select the most relevant features.",
