-Every test compiles Kotlin/Native → `libcalculator.so` (200+ exported symbols) → loads via FFM `MethodHandle` → verifies on JVM. Zero mocks — all 930+ tests cross the real native boundary. Includes 25 load tests (500K+ FFM calls), concurrent stress tests (10 threads), 110+ suspend function tests with cancellation (incl. ByteArray, DataClass, List, Set, Map), and 50+ Flow tests (including `Flow<DataClass>`).
