Specify an excplicit package name to intent(s)

Right now I have to include the package name manually to an intent:
```kotlin
val myIntent = Intent(context, Class.forName("my.pkg.name.MyActivity")).apply {
setPackage(context.packageName) // API 34+
}

ProcessPhoenix.triggerRebirth(context, myIntent)
```

Start at the ProcessPhoenix.triggerRebirth entry point shown in the issue and inspect how the restart Intent is constructed. Verify the Android 14 requirement for an explicit package, then add coverage for the affected behavior and confirm that the resulting intent includes the package name.
