Windows installer and Linux AppImage carry their engines; a runner probe

Both build on packaging/stage.sh. The NSIS installer takes the staged
folder and removes only what it laid out; installer.sh drives it. The
AppImage gives linuxdeploy the app, the workers and libcef.so.
ElyPDF's test window installs the app's menus first, as ElyTree's
does. probe.yml reports what each Gitea runner holds.
