Usage: tests/smoke_appimage.sh PATH_TO_APPIMAGE [SECONDS]

Runs an Avida-ED AppImage long enough to verify wrapper startup, embedded HTTP
serving, WebView page load, and absence of proxied JavaScript errors.

The app normally keeps running until its window closes, so timeout exit code 124
is accepted after the expected load signals appear.
