Test all public methods with 100% coverage: - AddNode: updates ring, is idempotent, handles multiple nodes - RemoveNode: updates ring, handles non-existent nodes - GetNode: returns consistent results, handles empty ring and single node - GetNodes and IsEmpty helper methods Distribution tests verify: - Balanced key distribution across nodes (< 25% deviation) - Minimal key movement when adding nodes (< 35% moved) - Virtual nodes improve distribution (CV < 15%) - Ring behavior with 100+ nodes Includes benchmarks for GetNode, AddNode, and distribution operations.
