fix: include production node_modules in packaged app

Remove !node_modules from electron-builder files config so production
dependencies (like electron-pixel-picker) are automatically included
in the asar. electron-builder already excludes devDependencies by
default — the blanket exclusion was preventing all npm packages from
being available at runtime in packaged builds.
