// optionalDependency: @colbymchenry/codegraph-<platform>-<arch>. npm installs
// only the one matching the host, via each package's `os`/`cpu` fields (the
// esbuild pattern). This shim — run by the user's OWN Node — locates that bundle
// and execs its launcher, so the real work always runs on the bundled Node 24
// (with node:sqlite), regardless of the user's Node version. The user's Node is
// only ever a launcher; even an ancient version can run this file.
//
// Wired up at release time as the main package's `bin`:
//   "bin": { "codegraph": "scripts/npm-shim.js" }
// with the platform packages listed in `optionalDependencies`.
