Function named_edge_count

tests/test_pipeline.c:1096–1121

Count only edges of `edge_type` between the exact named source/target nodes. * The parity and incremental guards deliberately use unique symbol names, so * this canonicalizes across independent stores without depending on node IDs * or project-prefixed qualified names. */
