agra 12bf61a9fc std: restructure step 3 — ffi/ moves, build.sx, math dir spelling, fixtures
- objc.sx, objc_block.sx (from std/) + sdl3/opengl/raylib/stb/stb_truetype/
  wasm vendor bindings (from modules/ root) -> modules/ffi/
- std/uikit.sx deleted: platform/uikit.sx already declares UIApplicationMain
  and imports objc; '#framework "UIKit"' cannot live in a file imported on
  macOS targets (unconditional link directive, UIKit is iOS-only), so the
  three iOS-only examples carry the 3-line glue inline. 1607/1608/1616 also
  un-rotted (dead ns_string -> 'xx "..."' Into conversions, callconv(.c)
  msgSend fn-ptrs) — all three build for ios-sim/ios again.
- math/math.sx -> math/scalar.sx; one spelling '#import "modules/math"'
  everywhere (4 pinned IR snapshots regenerated: dir import adds Vec2/Mat4
  to the type tables).
- compiler.sx -> build.sx (imports, CLAUDE.md bundling table, specs.md).
- testpkg/ + test_c.sx -> tests/fixtures/ (resolve CWD-relative from repo
  root, same as vendors/).
- library-internal imports use full modules/... paths (std.sx tail,
  platform/bundle.sx, fixtures).

// ffi-objc-arc-01 — M4.A smoke test for NSObject + autoreleasepool.
//
// Exercises:
// 1. NSObject is declared in std/objc.sx and reachable from user code.
// `obj.retain()` / `obj.release()` dispatch via the M2.3 #extends-aware
// method chain. Pattern: `defer obj.release();` as the canonical
// sx idiom for owned Obj-C handles.
// 2. `autoreleasepool(body)` stdlib helper wraps `body` in a
// push/defer-pop pair so Foundation factory returns drain at block
// end.
//
// macOS-only — libobjc + NSObject must be available at runtime.
#import "modules/std.sx";
#import "modules/ffi/objc.sx";
#import "modules/build.sx";
main :: () -> s32 {
inline if OS == .macos {
// Manual retain/release on an NSObject instance — the
// `defer obj.release();` pattern is the canonical sx idiom.
obj := NSObject.alloc().init();
if obj == null { print("FAIL: alloc null\n"); return 1; }
defer obj.release();
// Bump the count and drop the extra; refcount math stays balanced.
_ = obj.retain();
obj.release();
print("retain/release: ok\n");
// autoreleasepool helper round-trip — just exercise that the
// push/pop pair executes. We don't have a side-effect to observe
// (NSObject.new returns a +1 retained, NOT autoreleased), so this
// is a smoke test of the helper's shape, not the runtime
// behavior.
autoreleasepool(() => {
inner := NSObject.new();

inner.release();

});
