Summary

• Trigger only on release publication.
• Build clap-macos-arm64, clap-windows-amd64-cpu.exe, clap-windows-arm64-cpu.exe, clap-linux-amd64-cpu, and clap-linux-arm64-cpu on native runners.
• Each matrix build uploads its own binary directly to the release as soon as it finishes; no intermediate Actions artifacts or separate upload job.
• Remove Smoke test and Verify macOS architecture steps as requested.
• Use static bundled dependencies and embedded Metal shaders on macOS; use ClangCL for portable Windows ARM64 builds.

Verification

• actionlint and git diff --check passed for the current workflow.
• All five platform builds passed before removing the requested verification steps; build configuration is unchanged.
• Actual release uploads remain untested until a release is published.
