Fixes #8639.

On iOS 27 and tvOS 27, UIKit stops every app that hasn't adopted the UIScene lifecycle at launch, before setup():

EXC_BREAKPOINT … UIKitCore`___UIApplicationEvaluateRuntimeIssueForNoSceneLifecycleAdoption_block_invoke

ofxiOS still used the app-delegate lifecycle from before iOS 13, so no openFrameworks iOS or tvOS app could start on them.

Change

• ofxiOSSceneDelegate (in ofAppiOSWindow.mm, which builds for iOS and tvOS, so no project files change):
  • When the scene connects, it attaches the window the app delegate already created in applicationDidFinishLaunching: (window.windowScene = scene) and shows it.
  • It forwards sceneDidBecomeActive / sceneWillResignActive / sceneWillEnterForeground / sceneDidEnterBackground to the app delegate's applicationDidBecomeActive: etc. UIKit no longer calls those in scene-based apps, and ofxiOS uses them for focus, animation and glFinish().
  • It forwards opened URLs (scene:openURLContexts:, including the launch URL) to application:openURL:options:, or on iOS to application:handleOpenURL:.
• Template Info.plists (scripts/templates/ios/ofxiOS-Info.plist, scripts/templates/tvOS/ofxtvOS-Info.plist): a single-scene UIApplicationSceneManifest that names ofxiOSSceneDelegate. Naming it in the plist, rather than returning it from the app delegate, means it also works with custom app delegates (ofAppiOSWindow::startAppWithDelegate) that don't subclass ofxiOSAppDelegate.

ofxiOSAppDelegate, ofxtvOSAppDelegate and their subclasses are unchanged. They still create the window and view controller in applicationDidFinishLaunching:.

Existing projects keep their own ofxiOS-Info.plist / ofxtvOS-Info.plist, so they need the same UIApplicationSceneManifest entry added to run on iOS / tvOS 27.

Tested

Xcode 27.1 on the iOS 27.2 and tvOS 27.2 Simulators. I built each template's app with CMake, switching windowControllerType between GLKit and Core Animation, and rebuilt the core with this change:

Template	Controller	Launch	setup() / first draw()	Screen
ios	GL_KIT	✅ running after 20 s	✅ / ✅ 1398×2034	✅ full screen, no status bar
ios	CORE_ANIMATION	✅	✅ / ✅ 1398×2034	✅
tvOS	GL_KIT	✅	✅ / ✅	✅ full screen
tvOS	CORE_ANIMATION	✅	✅ / ✅	✅

Before the change, both templates stopped at launch with the EXC_BREAKPOINT above.

Not tested here:

• a custom app delegate, external displays, and URL opening;
• devices (Simulators only), and iOS / tvOS 26 and earlier.

The scene APIs exist since iOS / tvOS 13, so older versions should run the same code.

Separate, maybe existing: on tvOS, ofGetWidth() / ofGetHeight() report 1080 × 1920 (portrait) while the app correctly fills the 1920 × 1080 screen. No tvOS 27 app could run before this change, so I couldn't compare. ofxiOS's orientation handling treats tvOS like a portrait device, so it's probably not new, but it's worth checking.

Looks like this broke on tvOS.
