Description: Implements a Super Learner framework for right-censored survival data. 
    The package fits convex combinations of parametric, semiparametric, and machine 
    learning survival learners by minimizing cross-validated risk using inverse 
    probability of censoring weighting (IPCW). It provides tools for automated 
    hyperparameter grid search, high-dimensional variable screening, and evaluation 
    of prediction performance using metrics such as the Brier score, Uno's C-index, 
    and time-dependent area under the curve (AUC). Additional utilities support 
    model interpretation for survival ensembles, including Shapley additive 
    explanations (SHAP), and estimation of covariate-adjusted restricted mean 
    survival time (RMST) contrasts. The methodology is related to treatment-specific 
    survival curve estimation using machine learning described by Westling, Luedtke, 
    Gilbert and Carone (2024) <doi:10.1080/01621459.2023.2205060>, and the unified 
    ensemble framework described in Lyu et al. (2026) <doi:10.64898/2026.03.11.711010>.
