CI: give the Linux arm64 release archive its own name

[timosachsenberg]

Both Linux jobs (ubuntu-latest and ubuntu-24.04-arm) have runner.os == 'Linux', so both packaged and uploaded contrib_build-Linux.tar.gz to the same release. The job that finished last replaced the other job's archive. Releases 2026-09-28-154454 and 2026-03-25-183345 contain the x64 archive and no arm64 archive.

Set the archive name per matrix entry in ARCHIVE_NAME. The arm64 archive is now contrib_build-Linux-arm64.tar.gz. The x64 Linux, macOS and Windows names do not change, because the pyOpenMS wheel workflow and the app repositories download them by name.

Fixes #188

📝 Walkthrough

Walkthrough

The workflow matrix now assigns an explicit archive filename to each platform. Packaging and the Windows, macOS, and Linux release steps use that filename. Linux x64 and arm64 therefore map to distinct archive names.

Changes

Release archive naming

Layer / File(s)	Summary
Assign and use platform archive names .github/workflows/main.yml	The build matrix assigns each platform an archive name. Packaging and release steps use that value to name and select the archive. Linux x64 and arm64 receive distinct names.

Priority: ➖ Normal

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to 67426

The workflow keeps the existing x64 Linux, macOS, and Windows archive names while giving Linux arm64 a separate asset. No release-archive risk remains that warrants delaying merge.

Review details

Before / after behavior

• observed — Modified behavior in .github/workflows/main.yml: The matrix adds per-OS archive names, including a distinct Linux arm64 name; Ubuntu x64, macOS, and Windows retain their respective platform names. The existing OS-specific CMake arguments and versions remain unchanged.
• observed — Modified behavior in .github/workflows/main.yml: Packaging now names the tarball with matrix.ARCHIVE_NAME instead of runner.os, so the Linux x64 and arm64 jobs produce differently named archives.
• observed — Modified behavior in .github/workflows/main.yml: The Windows release step now selects the packaged file using matrix.ARCHIVE_NAME instead of a filename derived from runner.os.
• observed — Modified behavior in .github/workflows/main.yml: The Mac and Linux release step now selects the packaged file using matrix.ARCHIVE_NAME instead of a filename derived from runner.os.

_{A rabbit packs the Linux pair,
With names that show which builds are there.
Mac and Windows keep their own,
Each archive has a name alone.
The release shelf now holds them clear.}
