Issues

• GFQL Cypher: whole-node results of traversal patterns return wrong nodes (relationship uniqueness, variable length, undirected hops)

• compute_igraph / CALL graphistry.igraph.*: fails with 'Vertex attribute conflict' when nodes have a name column

• GFQL Cypher: pattern predicate in WHERE breaks aggregates (count(*) is 0 or every row on pandas, errors on cuDF)

• GFQL Cypher: a backslash in a string literal is doubled under NOT / OR, so the predicate matches the wrong rows
