Description: Maximum likelihood estimation of component lifetime parameters
    from system-level observations of k-out-of-n systems. Supports
    exponential and Weibull component distributions under multiple observation
    schemes: Scheme 0 (system lifetime only), Scheme 1 (periodic inspection),
    and Scheme 2 (complete monitoring). Provides an EM algorithm for Weibull
    parallel systems and Fisher information comparison across schemes. The
    k-out-of-n framework unifies series (k=1) and parallel (k=m) systems as
    a censoring problem on component lifetimes. Conforms to the
    'likelihood.model' generics and returns fitted objects compatible with
    'algebraic.mle'. The data-generating process and topology infrastructure
    (system survival, density, signature, structure function, importance
    measures) are delegated to the 'dist.structure' package; 'kofn' focuses
    exclusively on inference for the k-out-of-n family.
