#
# Triggered by a semver tag (e.g. v1.2.3).
#
# Jobs:
#   build-windows  — compiles WinToastWrapper.dll for win-x64 / win-x86 / win-arm64
#                    using MSBuild on a Windows runner.
#   build-macos    — compiles libMacNotifyWrapper.dylib for osx-arm64 and osx-x64
#                    using clang cross-compilation on a macOS runner.
#   pack           — downloads all native artifacts, packs the NuGet package with the
#                    tag version, creates a GitHub Release, and optionally pushes to
#                    NuGet.org (requires the NUGET_API_KEY repository secret).
