- PathFinder.bfs_shortest_path() and dijkstra_shortest_path() gain a
directed: bool = True parameter. When False, a temporary undirected
view (graph.to_undirected()) is used for traversal only; the original
directed edges are preserved and returned in the response.
- _make_undirected_view() helper added to PathFinder; falls back safely
for non-NetworkX graph types.
- GET /api/graph/node/{id}/path exposes ?directed=false query param.
- PathResponse gains a directed: bool field echoing the mode used.
- Route now returns 404 on empty path (previously returned 200 with
path: []).
- 21 new tests: 12 unit (TestBidirectionalPathFinding) + 9 API-level
(TestBidirectionalPathRoute). All 120 tests pass.
- CHANGELOG updated under [Unreleased].
