/**
 * OmniRoute — Postinstall Native Module Rebuild
 *
 * The npm package ships with a Next.js standalone build that includes
 * better-sqlite3 compiled for the build platform (Linux x64).
 * This script detects platform mismatches and rebuilds the native
 * module for the user's actual OS/architecture.
 *
 * Fixes: https://github.com/diegosouzapw/OmniRoute/issues/129
