// electron-builder 26 special-excludes node_modules from extraResources (25 did
// not), so the bundled 9Router - a Next.js standalone whose server.js does
// require('next') - ships WITHOUT its deps. The result: 9Router dies with
// "Cannot find module 'next'", never binds :20128, and the Models tab spins on
// "Starting subscription service..." forever. We copy router/node_modules into
// the packed app HERE rather than after electron-builder finishes, because
// afterPack runs BEFORE code-signing: on macOS the whole .app is sealed by the
// signature, so injecting files post-sign would invalidate it. The .next dotdir
// is handled by the package.json extraResources filter; only node_modules needs
// this rescue.
