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).

// Chained foreign-class method dispatch: `Cls.static().instance(...)`
// resolves the inner call's return type so the outer dispatch's
// receiver type is known. Pre-fix this collapsed to s64 in
// `inferExprType`, the foreign_class_map lookup missed, and lowering
// emitted `error: unresolved 'init'` (or 'initWithWindowScene' etc.)
// — see issues/0043 for the chess uikit.sx C4 migration that hit it.
//
// Two return-type shapes covered: explicit `*ClassName` (alloc here)
// and `*Self` (init). Both must propagate through the chain so the
// next `.method(...)` finds the foreign-class declaration.
