//! Advanced graph algorithms module.
//!
//! Provides algorithms beyond basic graph traversal: shortest paths with negative weights,
//! max-flow / min-cut, bipartite matching (Hopcroft-Karp), MST (Kruskal + Prim),
//! Tarjan's SCC, topological sort, bipartiteness check, and greedy chromatic approximation.
