// onesignal:managed v1 — debug-only verification helper.
// File: OneSignalSetupVerification.swift
// Call site: OneSignalSetupVerification.install() — call once from your launch
//   context (AppDelegate application(_:didFinishLaunchingWithOptions:) or the
//   SwiftUI App init()), right after OneSignal.initialize(...).
// The #if DEBUG guard compiles this file out of release builds, so the file is
// safe to keep. Delete it and its single install() call only if you want to.
//
// What it does in a debug build:
//   1. Requests push permission — the only place the integration prompts.
//   2. Watches the push subscription and prints the subscription ID once the
//      device registers. The verify skill confirms the registration
//      server-side and sends the test push from chat — this file makes no
//      network call.
