Description: Implements generalized hybrid contrast coding methods for
        K-level categorical predictors in linear models as established
        by Obulezi (2026)[cite: 3]. The package automates design matrix
        construction mixing dummy indicators and composite group
        contrasts, checks rank constraints via singular value
        decomposition, computes closed-form OLS parameter mappings, and
        estimates robust heteroscedastic covariance matrices[cite: 3].
