%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.
