ci(release): Add macOS portable packaging pipeline

Extend release workflow with per-architecture macOS packaging jobs, universal artifact assembly, and portable artifact verification. Publish arm64, x64, and universal tarballs plus SHA256 files to GitHub Releases.

Keep existing npm and MCP registry release flow intact while wiring version output from the release job into portable packaging stages.
