Probe AppImage input drift

[AnthonyRonning]

README-only probe PR to verify that the current CI failures are caused by mutable external Linux AppImage tooling inputs rather than the Windows desktop port changes in #520. This intentionally changes no code, workflows, flakes, or lockfiles.

Poem

🐰 A marker hops into the README so fine,
Tracking drift through the CI pipeline line,
One small comment, yet it helps us see,
Where inputs shift in our symphony! ✨
