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).

// `#jni_main` pipeline slice 2 (PLAN-FFI.md): the compiler renders a
// `.java` source for a `#jni_main #jni_class("...")` declaration, runs
// `javac` + `d8`, and bundles `classes.dex` into the APK.
//
// Slice 2 only wires the plumbing — the manifest still points at
// `android.app.NativeActivity`, so the user's class isn't loaded at
// runtime. Slice 3 (manifest synthesis) and slice 4 (RegisterNatives)
// land in follow-up commits.
//
// Build to inspect APK contents (requires Android SDK + JDK):
// /Users/agra/projects/sx/zig-out/bin/sx build --target android \
// --apk /tmp/sxjnimain.apk --bundle-id co.swipelab.sxjnimain \
// -o /tmp/libsxjnimain.so examples/ffi-jni-main-01-emit.sx
// unzip -l /tmp/sxjnimain.apk | grep classes.dex
#import "modules/std.sx";
#import "modules/build.sx";
// `*Bundle` resolves through the class registry to `android.os.Bundle`
// in the emitted Java — needed for `onCreate`'s @Override to match
// NativeActivity's superclass signature.
Bundle :: #foreign #jni_class("android/os/Bundle") { }
// `#jni_main` flags this as the launchable Android Activity class. The
// `onCreate` body is empty for now — slice 4 wires `RegisterNatives`
// so the `sx_onCreate` native delegate actually binds to a sx-side fn.
