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.2c / A.3 — instance-method body lowering on sx-defined
// `#objc_class`.
//
// The Obj-C runtime invokes class methods via the IMP pointers
// wired up in M1.2 A.4. No sx-side call path drives lazy lowering,
// so the eager pass `lowerObjcDefinedClassMethods` walks the
// `objc_defined_class_cache` and force-lowers every bodied method
// after Pass 1 finishes.
//
// `*Self` substitution (A.2b) routes the param's pointee type to
// the hidden state-struct `__<ClassName>State`. `self.counter`
// then resolves as a plain struct field access — A.3's "free if
// types align". The IR snapshot pins the round-trip:
//
// define internal void @SxFoo.bump(ptr __sx_ctx, ptr self) {
// %gep = getelementptr inbounds { i32 }, ptr %self, 0, 0
// %v = load i32, ptr %gep
// %inc = add i32 %v, 1
// store i32 %inc, ptr %gep
// ret void
// }
//
// IMP-trampoline emission (the C-ABI shim that the Obj-C runtime
// calls and that reads the `__sx_state` ivar) lands separately
// in M1.2 A.4 alongside class-pair init. Runtime dispatch
// (M1.2 A.7) stays gated until then.
