React-based graph visualization library for Hydro dataflow programs

/**
 * @fileoverview ELK Bridge - Clean interface between VisState and ELK
 *
 * This bridge implements the core architectural principle:
 * - VisState contains ALL data (nodes, edges, containers)
 * - ELK gets visible elements only through visibleEdges (hyperedges included transparently)
 * - ELK returns layout positions that get applied back to VisState
