调研方向

The runtime failure occurs while building and verifying the NavMesh for ./examples/rod_with_normals; the log reports a repeated non-start halfedge in test_neighbours. Start by running that example and tracing the NavMesh verification path that emits this error. Done means the example completes NavMesh verification without the repeated-halfedge exception.
