Refactor release workflow to use artifacts for multi-platform builds

[T3pp31]

Summary

Refactored the GitHub Actions release workflow to decouple binary building from release creation. The workflow now uploads built binaries as artifacts and uses a separate job to collect and release them, improving workflow efficiency and maintainability.

Key Changes

• Build job: Added artifact upload step to store compiled binaries for each target platform
• New release job: Created a separate release job that depends on build to:
  • Download all artifacts from the build matrix
  • Merge multiple artifacts into a single directory
  • Upload all binaries to GitHub Releases in one step
• Removed matrix dependency: The release step no longer depends on the build matrix, simplifying the release logic

Implementation Details

• Uses actions/upload-artifact@v4 to store binaries with target platform as the artifact name
• Uses actions/download-artifact@v4 with merge-multiple: true to consolidate all platform binaries
• The release job uses needs: [build] to ensure all build jobs complete before attempting release
• Simplified the release file pattern from matrix-dependent paths to a simple artifacts/* glob
