ANR in Mapbox native library during mutex lock (libmapbox-common.so, libmapbox-maps.so)

Nobody has claimed this yet.

## Environment

- Android OS version: 11,12,13
- Devices affected: Samsung, Xiaomi, Vivo
- Maps SDK Version: 11.12.0

## Observed behavior and steps to reproduce

We're encountering a critical ANR on some devices, seemingly caused during native library initialization inside the Mapbox Maps SDK v10+. This issue happens while loading `libmapbox-common.so` and `libmapbox-maps.so`, particularly around a mutex lock on a background thread.

We are not calling `Mapbox.getInstance()` explicitly, and are using Mapbox v11.12.0 via `MapView` in Fragment.

## Expected behavior

The app should run smoothly without freezing or causing any delay in the UI thread. No ANR dialog should be shown.

```

Please investigate whether there's a native mutex deadlock or race condition in the latest native libraries, possibly related to the shared `libc++_shared.so` or `libmapbox-common.so`. Any guidance or patch would be appreciated.

Start at the AndroidX Startup entry points InitializationProvider and BaseMapboxInitializer, then follow MapboxMapsInitializerImpl.create into MapboxLibraryLoader.load. Compare the native loading stack involving libc++_shared.so, libmapbox-common.so, and libmapbox-maps.so across the reported Android versions and devices. Done means identifying a reproducible deadlock or race cause and documenting or validating a fix.
