Steps to Reproduce

The Sentry SDK is capturing an unreasonably low number of warm starts, and the start duration consistently shows cold < warm.

This happens for a specific Activity in my app that is configured with android:launchMode="singleTask".

I suspect that the SDK is misclassifying app startup types in AppStartMetrics.java → onActivityCreated() (https://github.com/getsentry/sentry-java/blob/23b6ef97e8f491b9bf73bde3b73453030fc3d973/sentry-android-core/src/main/java/io/sentry/android/core/performance/AppStartMetrics.java#L364) as the singleTask launch mode would always create Activity instances with savedInstanceState = null, causing all app launches to be classified as cold starts.

Expected Result

warm start < cold start

Actual Result

warm start > cold start
