v0.8.0

Minor Changes

• 8b97c9b Thanks @davidkpiano! - Add port support for nodes and edges, enabling dataflow/node-editor graphs (Node-RED, Unreal Blueprints, ComfyUI).

  • Add GraphEntityConfig, GraphEntity, VisualGraphEntity base interfaces (DRY shared props for nodes, edges, ports)
  • Add PortConfig<P>, GraphPort<P>, VisualPort<P> types with generic data parameter
  • Add P (port data) as 4th generic to Graph<N, E, G, P> and all related types
  • Add ports?: PortConfig[] on NodeConfig, ports?: GraphPort[] on GraphNode
  • Add sourcePort? / targetPort? (port name strings) on EdgeConfig and GraphEdge
  • Add createGraphPort() factory
  • Add port validation: duplicate port names rejected, addEdge/updateEdge validate port existence
  • Add port queries: getPort(), getPorts(), getEdgesByPort()
  • ELK adapter: round-trip ports (name ↔ ELK port id, direction ↔ org.eclipse.elk.port.side)
  • xyflow adapter: sourcePort ↔ sourceHandle, targetPort ↔ targetHandle
