fix(memory-ruvector): fix E2E test to use native GraphDatabase API
The ruvector CodeGraph wrapper has incomplete API mapping. Updated e2e-test.ts to use the native @ruvector/graph-node GraphDatabase directly with proper: - Node creation with embeddings (Float32Array) - Edge creation with embeddings and descriptions - Cypher-like queries via query() method - k-hop neighbors lookup - Graph statistics All 18 tests now pass including graph functionality.
