Commit B fixes a real correctness bug in the core Rank Centrality scoring (wrong d_max divisor causing bipartite oscillation and uniform scores on star topologies), aligns the math with the cited paper, and adds durable Rust + Clojure regression tests with fixtures. Commit A is almost entirely rustfmt whitespace/import churn plus minor tooling pins and a trivial CSS dedup, which adds negligible lasting product value.
