feat(ci): add macOS ARM build, test and release

- Add build-macos job to build.yml and release.yml (macos-15 ARM)
- Use Apple Clang (Xcode 16) for full C++20 ranges support
- Update slang submodule to latest for Apple Clang compatibility
- macdeployqt on cmake-generated .app bundle, package as DMG
- DMG contains QSoC.app (GUI) + standalone qsoc CLI binary
- Smoke test with inline-generated CSV bus and Verilog module
- Disable mimalloc on macOS (same as Windows)
- Set CMAKE_POLICY_VERSION_MINIMUM for yaml-cpp compatibility
