[v4 beta] Android link error on React Native 0.82: undefined symbol folly::detail::ScopeGuardImplBase::terminate() #931

Versions: @lodev09/react-native-true-sheet 4.0.0-beta.25 (also every beta from ~beta.15; beta.10 and earlier don't have it), React Native 0.82.1, New Architecture, AGP/Gradle 9, NDK r27.

What happens: ./gradlew :app:assembleDebug fails in :app:buildCMakeDebug[arm64-v8a] while linking libreact_codegen_TrueSheetSpec.so:

ld.lld: error: undefined symbol: folly::detail::ScopeGuardImplBase::terminate()
clang++: error: linker command failed with exit code 1

Cause: common/cpp/react/renderer/components/TrueSheetSpec/TrueSheetContentViewShadowNode.cpp includes <folly/ScopeGuard.h> and calls folly::makeGuard(...) (around line 98). Its out-of-line terminate() is defined in folly's ScopeGuard.cpp, which RN 0.82's Android prefab doesn't export to third-party libraries. The example app is on RN 0.86, where the symbol presumably resolves, while the v4 migration guide documents RN 0.82+ as supported.

Suggested fix: replace the folly guard with a small local RAII struct, e.g.

struct RestoreMeasurement { ~RestoreMeasurement() { gIsMeasuringNaturalHeight = false; } } restoreMeasurement;

or raise the documented minimum React Native version for Android.

iOS builds fine on the same versions.
