Description: Implements weighted double score matching (WDSM) for estimating
    population-level causal effects from complex survey data. Combines
    propensity scores and prognostic scores with survey design weights for
    matching, survey-weighted imputation within match sets, and Hajek
    normalization to target the population average treatment effect (PATE) and
    the population average treatment effect on the treated (PATT). Supports
    both retrospective (treatment-dependent) and prospective
    (treatment-independent) sampling designs. Uses propensity probabilities
    and arm-specific prognostic scores for matching, with a complete quadratic
    bias correction in each arm's double score. Provides linearization-based
    multinomial replication variance estimates and centered normal Wald
    confidence intervals, retaining the original matching reuse coefficients
    without re-matching. Supplied scores can be held fixed for inference
    conditional on those scores. This weight-only interface does not encode
    survey strata, clusters, or design-specific replicate weights.
