Description: Implements four support vector regression (SVR) models
        derived from a unified mathematical framework for
        percentage-error loss functions: epsilon-SVR minimizing the
        mean absolute percentage error (MAPE), its symmetric kernel
        extension, least-squares SVR (LS-SVR) minimizing the root mean
        square percentage error (RMSPE), and its symmetric counterpart.
        All models require strictly positive targets. The epsilon-SVR
        models are solved via a built-in sequential minimal
        optimization (SMO) algorithm (with 'osqp' available as an
        optional alternative backend) and the LS-SVR models via a
        linear system (base R). See Benavides-Herrera et al. (2026)
        <doi:10.3390/math14101679> for the mathematical derivations.
