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).

// Variadic heterogeneous type packs — step 4A final-slice
// follow-up. `type_name(<dynamic-arg>)` where the argument is
// NOT a static type expression (e.g. `list[i]` indexing into
// a `$args`-derived `[]Type` slice) silently folded to "s64"
// because `resolveTypeArg`'s catch-all `else => .s64` lied —
// the kind of silent unimplemented arm the project's REJECTED
// PATTERNS forbid.
//
// The fix: `tryLowerReflectionCall` now splits static vs
// dynamic args via `isStaticTypeArg(node)`. Static → fold to
// const_string at lower time (today's fast path). Dynamic →
// emit `callBuiltin(.type_name, [arg_ref])` for the interp's
// runtime arm to handle.
//
// Type values are comptime-only — the dynamic path only works
// inside a comptime context (`#run` / `#insert`). The test
// runs `walk(42, "hi")` at `#run` time and prints the result.
