Summary: The RedBox auto-retry timer could fire a reload while the app was in the background. That reload restarts the instance and re-initializes native modules; a module requiring main-queue setup is dispatched synchronously onto the main queue, which is itself blocked inside the reload, deadlocking the app until the watchdog terminates it. Gate the countdown in `autoRetryTick` on foreground state, so the timer only advances (and eventually reloads) while the app is active. In app extensions `RCTSharedApplication()` is nil, which reads as active and preserves the prior behavior.

Summary:
The RedBox auto-retry timer could fire a reload while the app was in the
background. That reload restarts the instance and re-initializes native
modules; a module requiring main-queue setup is dispatched synchronously onto
the main queue, which is itself blocked inside the reload, deadlocking the app
until the watchdog terminates it.

RCTSharedApplication()is nil, which reads as active and preserves the priorbehavior.
