Subject: [PATCH] Cover `react/renderer/viewtransition:viewtransition` with
 Stable API guards

Summary:
Classifies `react/renderer/viewtransition:viewtransition` as a private target under the C++ stable API three-tier visibility model. Adds `#include <react/cxxstableapi/PrivateGuard.h>` to all three headers in the module and declares the guard dependency in the build config (parent podspec is already configured).

Changelog: [Internal]
