Description: Provides an interface for quantitative-genetic models in 'R',
    backed by the 'HSquared.jl' engine for 'Julia'. Fits Gaussian pedigree animal models
    by restricted maximum likelihood, using
    average-information restricted maximum likelihood (AI-REML; Gilmour et al.
    (1995) <doi:10.2307/2533274>) for the univariate model. Returns heritability, variance components, breeding
    values, and covariance and correlation matrices for multivariate models.
    Formula and pedigree validation can run without 'Julia'. Model fitting requires a local 'Julia'
    and 'HSquared.jl'; use hs_control(engine = "validate") to preview the model
    contract without fitting. What you may report is listed on the package
    article 'Can I fit and report this?', not in validation_status(), which is
    a developer evidence table. Model-specific restrictions are documented in
    that article. Uncertainty intervals are not coverage-calibrated.
