/**
 * OmniRoute — Postinstall Native Module Fix
 *
 * The npm package ships with a Next.js standalone build that includes
 * better-sqlite3 compiled for the build platform (Linux x64) inside
 * app/node_modules/. However, npm also installs better-sqlite3 as a
 * top-level dependency (in the root node_modules/), correctly compiled
 * for the user's platform.
 *
 * This script copies the correctly-built native binary from the root
 * into the standalone app directory — no rebuild or build tools needed.
 *
 * Fixes: https://github.com/diegosouzapw/OmniRoute/issues/129
 * Fixes: https://github.com/diegosouzapw/OmniRoute/issues/321
 * Fixes: https://github.com/diegosouzapw/OmniRoute/issues/426
