fix(build): emit linux x86_64 tar.gz on every package run

The in-app updater installs the release asset matched by pickAsset
(tar.gz + linux + x86_64/amd64); the config only built AppImage+deb, so
plain 'npm run package' produced no updatable asset and required a second
electron-builder invocation plus a manual rename (as done for 0.1.13).
