ci: Revert to last known working configuration

- Restored the working .gitlab-ci.yml configuration
- Removed the problematic CMAKE_FLAGS variable approach
- Back to inline cmake command that was working
- Uses CachyOS with perl-digest-sha for proper shasum support
- Maintains all build optimizations and AppImage creation
- This should resolve the YAML parsing issues
