Description: Provides PLUS-derived extensions for positive and unlabeled (PU)
    learning from unbalanced cases and sparse structures, based on Zhou et al.
    (2022) <doi:10.1371/journal.pcbi.1009956>. Iteratively relabels unlabeled
    observations via penalised logistic regression and pseudo-label updates,
    then refits a final sparse model.
    Includes weighted bootstrap sampling, convergence diagnostics, prediction,
    coefficient extraction, and assessment utilities.
