// Note: UNUserNotificationCenter requires the binary to live inside a signed
// app bundle at runtime. Invoked as a bare CLI, it throws
// NSInternalInconsistencyException about `bundleProxyForCurrentProcess is
// nil`. Packaging/signing is owned by eliza-devops (deferred per T8b); this
// test therefore asserts the helper builds and runs, and accepts the known
// bundle-proxy error as a documented "unbundled" signal.
