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).

// Phase 1 step 1.3 (PLAN-FFI.md): smallest end-to-end `#objc_call`.
// Void return, nil receiver — Obj-C runtime guarantees that messages
// to nil are no-ops with a zero result, so we don't need to set up
// a real object graph to exercise the lowering surface.
//
// Today (step 1.3, test-add): codegen rejects the FfiIntrinsicCall
// AST node. Snapshot pins the failure mode.
// Next (step 1.3, make-green): emit_llvm.zig synthesizes
// %sel = call ptr @sel_registerName(ptr @"sel:init")
// call void @objc_msgSend(ptr null, ptr %sel)
// per call site (no selector interning until step 1.5).
