/**
 * @file postinstall.js
 * @description Root `postinstall` hook: after a bare `npm install` at the repo
 * root, install the React client's dependencies too, so a single root install
 * yields a buildable/runnable tree (the client's fonts and build deps live in
 * `client/package.json`). The step is a safe no-op when the `client/` workspace
 * is absent — production/Docker stages that copy only the root manifest, the
 * MCP image's `file:..` link, and the published tarball all install without a
 * client checkout, and must not fail here. Skipped entirely under
 * `npm install --ignore-scripts` (run `cd client && npm install` manually then).
