name: LANCommander Launcher Tests — Update Visual Baselines

# Operator-triggered: re-renders every visual test on the CI host and commits the
# new screenshots over the committed Baselines/. Only runs when a human dispatches
# it from the Actions tab — never on push or PR — so accidental drift can't slip in.
