Changes in version 0.1.0 (2026-05-19)                  

  - Initial release on CRAN.
  - Core SMSN distribution functions: smsn_fit, smsn_density, smsn_cdf,
    smsn_quantile, smsn_rdist.
  - Decision-theoretic cutoff: cutoff_optimal, cutoff_youden,
    cutoff_risk, cutoff_phi.
  - Asymptotic inference: cutoff_variance, cutoff_ci,
    cutoff_identifiability.
  - Admissible interval tools: cutoff_admissible_interval,
    cutoff_boundary_check, cutoff_build_interval,
    cutoff_expand_interval_until_valid.
  - ROC analysis: smsn_roc, smsn_auc.
  - Monte Carlo simulation: mc_one_rep, mc_simulate_scenario,
    mc_run_all.
  - smsn_fit uses Richardson extrapolation (numDeriv::hessian) for the
    observed Fisher information matrix, critical for accurate variance
    estimation.
  - Implements the methodology of de Paula, Mouriño, and Dias Domingues
