CMakeLists.txt: - Native host build by default; Emscripten-target detection plumbed but WASM emit deferred to stream 7 (playground build script). - Header-only INTERFACE library `nisps_core`. - Host test executable `nisps_core_tests` compiled with -Wall -Wextra -Werror -Wpedantic (Chris's rules: clean build is non-negotiable). tests/cpp/test_helpers.hpp: - Minimal NISPS_TEST / NISPS_EXPECT / NISPS_EXPECT_NEAR macros, no external deps. Rationale documented in-file: Catch2/doctest would add ~10MB and 30s for what is currently <100 LOC of test runtime. 22 unit tests covering FixedBuffer (5), RingBuffer (5), Rng (7), math (5). All green; verified via `cmake --build nisps/build && ./nisps/build/nisps_core_tests`.
