chore: scaffold CMake build system
Add the CMake build for the Swift + C++ macOS port, mirroring the refix layout: deps/ modules (Platform, Flags, Sanitizers, FindUnity), per-module static libraries (usb, auth, mt76, gip, hid, api), a Swift app entry point with a pure C bridge header, and a Unity test suite behind BUILD_TESTING. Swift requires the Ninja or Xcode generator; a guard in CMakeLists.txt rejects anything else. Co-Authored-By: qwen (qwen/qwen3.8-27b@q2_k_xl): scaffolded CMake build + tests
