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).

// M1.2 A.4 — class-pair registration with the Obj-C runtime.
//
// Every sx-defined '#objc_class' produces a module-init constructor
// (registered in '@llvm.global_ctors' AND injected at the top of
// 'main' for the ORC JIT path) that calls:
//
// super = objc_getClass("NSObject")
// cls = objc_allocateClassPair(super, "SxFoo", 0)
// objc_registerClassPair(cls)
//
// After the constructor runs, 'objc_getClass("SxFoo")' returns the
// freshly registered class — the round-trip we verify below.
//
// Methods, the '__sx_state' ivar, and the '+alloc' / '-dealloc'
// overrides land in A.4b / A.5 / A.6; this slice just makes the
// class EXIST in the runtime.
#import "modules/std.sx";
#import "modules/build.sx";
