React-based graph visualization library for Hydro dataflow programs

/**
 * ELK State Manager (TypeScript port from working visualizer)
 *
 * This module provides wrapper functions that ensure all ELK layout interactions
 * are consistent with visualization state management as the single source of truth.
 *
 * Key principle: ELK should only ever calculate layouts based on the exact
 * visual state requirements, and return results that perfectly match those requirements.
