[FEATURE] Add Native Linux Packages to GitHub Releases

[Vysp3r]

Summary

Expand ProtonPlus GitHub releases with native Linux packages in addition to the existing AppImage, making ProtonPlus easier to install directly on more distributions and architectures.

Proposed Implementation

• Automatically build release packages through GitHub Actions when a new ProtonPlus version is tagged.

• Provide native packages for:

  • Debian/Ubuntu (.deb)
  • Fedora/RPM-based distributions (.rpm)
  • Arch Linux (.pkg.tar.zst)

• Keep the existing AppImage release artifact.

• Support both x86_64 and aarch64 where the application and required dependencies support them.

• Keep the native packaging definitions in the ProtonPlus repository so they can be versioned and maintained alongside the application.

• Generate packages from the same tagged ProtonPlus source to keep all release formats consistent.

• Add automated CI checks that install generated packages in clean environments and verify:

  • Package installation
  • ProtonPlus executable
  • Desktop/AppStream metadata
  • Icons
  • GSettings schemas
  • Required runtime dependencies

• Generate checksums for release artifacts.

• Publish a versioned source archive alongside binary packages.

• Allow distribution packaging such as the AUR package to consume the official ProtonPlus release sources/artifacts instead of maintaining separate upstream sources.

Goal

Provide consistent first-party ProtonPlus packages across major Linux distribution families, reduce reliance on third-party packaging, improve installation accessibility, and ensure release packages are automatically built and tested from the same official source.

@JanGalek I think this is important to add. Also I should be back around the 18 of September.

I agree, I already have experience with this in my project vamposer 😊
