Snapshot the iOS-refresh app (React Native shell + Objective-C/Swift iOS
runtime: AppDelegate, SceneDelegate, GamepadHaptics, ARMSX2Bridge) into
platforms/ios/. Delete its vendored PCSX2 core (794 pcsx2 + 150 common files)
and its vendored 3rdparty (~11.8k files); the repo-root core is the single
source of truth.
Relocate the genuine iOS-only core additions (MacOSStubs, QAProbe, TestHarness,
SifRingBuffer.h, common/PNGStub.cpp) into the root core, guarded by an
ARMSX2_IOS (CMAKE_SYSTEM_NAME==iOS) branch in pcsx2/CMakeLists.txt. The
NEON SPU2 sources are now shared by both arm64 mobile targets (ANDROID OR iOS).
Dropped cruft: *.try/*.ref backups, stray x86/microVU_impl.cpp, leaked
common/Android/* JNI files, and the adrenotools submodule (android-only).
Rewire the iOS native CMake to source the root {common,pcsx2,3rdparty} via an
ARMSX2_ROOT var, preserving all iOS-SDK/bundle/JIT-entitlement/Metal config.
NOT yet compiled against Xcode -- build validation is CI's job.
See REFACTOR_STATUS.md.
