fix(graph_search): avoid KeyError in BFS when a node has no outgoing edges (#506)

find_shortest_path_bfs indexed self.graph[value] directly while expanding
the queue. Any node reachable in the graph but not present as a key (a
leaf node with no outgoing edges, as in a typical adjacency list) raised
a KeyError instead of being treated as having no neighbors. The DFS
methods already handle this correctly via self.graph.get(start, []);
bring BFS in line with that and add a regression test.
