/**
 * Rope Trap Block - Trap that ties up entities when they walk on it.
 *
 *
 * Features:
 * - Flat block (1 pixel tall) placed on solid surfaces
 * - Can be loaded with bondage items by right-clicking
 * - When armed and entity walks on it, applies all stored items
 * - Destroys itself after triggering
 * - Preserves NBT data when broken
 *
 * Based on original BlockRopesTrap from 1.12.2
