* macOS: package the game as a proper SpaghettiKart.app bundle

Turns the bare Spaghettify executable into a self-contained SpaghettiKart.app:

- cmake/macos/apple_bundle.cmake: bundle metadata (using the existing
  Info.plist, which already described a bundle), app icon, runtime resources
  (config.yml, yamls, meta, spaghetti.o2r) into Contents/Resources, dylib
  relinking for local Homebrew builds (no-op with static vcpkg deps), and
  ad-hoc codesigning so the app launches without 'damaged app' warnings
- App icon: on Xcode 26+ the Icon Composer package (SpaghettiKartIcon.icon,
  drawn from the existing HM ship-kart icon.png art) compiles with actool
  into an Assets.car, giving the native Liquid Glass look on macOS 26+, plus
  a flattened icns for older systems; older Xcode falls back to the previous
  sips/iconutil flat icon. Supersedes the CreateOSXIcons target.
- Game.cpp: default SHIP_HOME to ~/Library/Application Support/SpaghettiKart
  on macOS so first-run extraction, saves, config, and mods land there
  instead of scattering into the user's home folder; a user-set SHIP_HOME
  still wins
- Info.plist: NSHighResolutionCapable for proper Retina rendering
- CI: mac jobs now ship the .app (ditto zip so the executable bit survives
  artifact upload)
- the yamls-next-to-exe copy is scoped to non-Darwin; on macOS those files
  live in Contents/Resources instead

* macOS: ship prebuilt icon artifacts instead of compiling them at build time

Commits the compiled Assets.car (Liquid Glass icon for macOS 26+) and the
flattened SpaghettiKart.icns, both built from the in-repo Icon Composer
package. The build now just copies them into the bundle, which removes the
actool machinery and the Xcode 26 requirement entirely: every build on any
machine, including CI, gets the real icon.

Also adds a staleness guard: the artifacts carry a hash stamp of the
icon.png they were made from, and if icon.png ever changes without them
being regenerated, the build automatically generates a flat icns from the
current icon.png instead, so updating the logo never requires any macOS
work and an outdated icon can never ship. Regeneration steps are documented
in apple_bundle.cmake.

* Rename the icon layer to ship-kart-layer.png

Group 2.png was the design tool's default layer name; name it for what it
is. Verified the Icon Composer package still compiles with actool after the
rename; the committed Assets.car is unaffected (compiled, self-contained).

* Fix macOS arm64 build: fmt consteval error in the TorchExternal sub-build

Torch's pinned spdlog bundles an fmt whose consteval format-string
checking fails to compile under newer AppleClang (Xcode 16+), breaking
the build-macos-arm64 CI job (the intel runner's older Xcode doesn't hit
it):

  error: call to consteval function 'fmt::basic_format_string<...>' is
  not a constant expression

Define FMT_CONSTEVAL as empty inside the Torch sub-build, falling back to
fmt's pre-C++20 constexpr checking. Injected via CMAKE_PROJECT_INCLUDE
because Torch's CMakeLists overwrites CMAKE_CXX_FLAGS, so plain flag
injection through CMAKE_ARGS is discarded. Scoped to AppleClang; no other
platform or compiler is affected, and the Torch pin is unchanged.

* Also neutralize FMT_CONSTEVAL for the game build (vcpkg spdlog/fmt)

With the TorchExternal fix in place, CI reaches the game build and hits
the same consteval error again, this time from the vcpkg-provided
spdlog/fmt headers (SPDLOG_FMT_EXTERNAL) under the runner's Xcode 26.5.
Apply the same AppleClang-scoped FMT_CONSTEVAL= define at the project
level so both layers compile.

* Pin vcpkg fmt to 10.2.1 (+ spdlog 1.14.1): fmt 11.0.2 can't compile on new AppleClang

The baseline's fmt 11.0.2 both fails to compile under newer AppleClang
(consteval format-string checking) and removed the #ifndef guard around
FMT_CONSTEVAL, so the AppleClang-scoped define from the previous commit
lands on the compile line but gets clobbered by fmt's own definition
(FMT_USE_CONSTEVAL is likewise unguarded in that version). No newer fmt
exists in the pinned baseline.

Override fmt to 10.2.1, which keeps the #ifndef guard, making the
existing define effective; spdlog moves to the matching 1.14.1 (1.15.x
requires fmt >= 11 headers).

Verified locally against the exact CI setup (vcpkg at baseline
2e58bb35ff, vcpkg toolchain file, Ninja): the previous failure reproduces
without this change and the full game builds cleanly with it.

* Add TODO markers for removing the fmt consteval workarounds

Requested in PR #712 review: mark all three workaround sites (project-level
define, Torch sub-build include, vcpkg fmt/spdlog pins) so they can be found
and removed together once the Torch pin is bumped past its spdlog/fmt update.
