Description: Imputes missing species trait data for comparative analyses
    by combining three sources of information: phylogenetic similarity
    (closely related species share similar traits), cross-trait
    correlations (observed traits inform missing ones), and optional
    environmental covariates (climate, habitat, geography). Handles
    continuous measurements, counts, binary variables, ordered categories,
    unordered categories, bounded proportions, zero-inflated counts, and
    compositional multi-proportion data in a single call. The method blends a
    phylogenetic baseline with a graph neural network correction; a
    per-trait gate calibrated on held-out data ensures the network only
    contributes when it improves on the baseline. Provides conformal
    prediction intervals for continuous, count, and ordinal traits and an
    experimental analysis-aware multiple-imputation workflow for one missing
    continuous covariate in Gaussian linear, binomial-logit, and Gaussian
    random-intercept models, with Rubin pooling limited to fixed effects.
    Stochastic graph-network and posterior-tree completions are prediction
    diagnostics rather than validated inferential imputations. Tested up to
    10,000 species.
    Bundled datasets include 300-species and 9,993-species bird-trait subsets
    with matching example phylogenetic trees.
