Description: Extends the 'algebraic.dist' distribution algebra to
    random variables with internal structure: coherent reliability
    systems decomposed into components arranged by a structure function
    (series, parallel, k-out-of-n, bridge, and arbitrary topologies via
    minimal path sets). Every 'dist_structure' object is a 'dist', so
    the full distribution algebra (mean, vcov, sampler, surv, cdf) works
    automatically via default methods that compose component-level
    distributions through the topology. Adds structural queries:
    structure function evaluation, minimal path and cut sets, system
    signature, critical states, dual, Birnbaum structural importance,
    and system reliability. Topology shortcut constructors (series_dist,
    parallel_dist, kofn_dist, bridge_dist) produce ready-to-use dists
    from component dists and a chosen structure.
