Subject: [PATCH] ci: Fix shasum wrapper to properly handle -a 256 arguments

- The AppImage build script uses 'shasum -a 256' but sha256sum doesn't accept -a flag
- Updated wrapper to detect and strip -a 256 arguments before calling sha256sum
- Added comprehensive testing of shasum compatibility in CI output
- This should resolve the 'sha256sum: invalid option -- a' error
- AppImage checksum verification should now work correctly
