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.
