/**
 * Comlink worker entry point.
 *
 * This module wraps the core sapling functions from `saplingCore.ts` with
 * Comlink so they can be called from the main thread across a Web Worker
 * (browser) or worker_threads (Node.js) boundary.
 *
 * All business logic lives in `saplingCore.ts`.  This file is:
 * - Compiled by tsc → dist/worker.js  (used by Node.js worker_threads)
 * - Bundled by webpack → dist/saplingWorker.js  (used by browser Web Workers)
