Description: Implements U-DDBART-IC, a unified Bayesian workflow for
        dynamic risk prediction from irregular longitudinal biomarkers
        when event times are interval-censored between clinical visits.
        The package turns long-format biomarker histories and
        patient-level interval endpoints L, R, C and delta into a
        discrete-time follow-up grid, summarises each landmark history
        with nine interpretable trajectory features (current, baseline
        and previous biomarker values, last visit gap, local slope,
        cumulative decline, best value, elapsed time and visit count),
        fits discrete-time interval hazards using optional logit-link
        Bayesian additive regression trees, a generalized linear model
        fallback, or a lightweight variational approximation,
        accumulates survival from the discrete-time product, and
        evaluates the interval-censored likelihood. Fitted models
        return landmark risk predictions over user-specified horizons
        with posterior or bootstrap uncertainty by evaluating survival
        ratios across fitted hazard draws. Utilities are provided for
        simulation, staged model fitting, plotting and summarising
        dynamic risk curves, IPCW Brier scores, cumulative/dynamic
        time-dependent area under the curve, calibration tables, and an
        anonymised chronic myeloid leukaemia molecular-monitoring
        example data set.
