// --- afterPack: strip bloat from the asar archive ---
// electron-builder v26 has a bug where the `files` config (negation-only,
// positive whitelist, AND FileSet with filter) is only applied to
// nodeModuleFilePatterns (node_modules filtering), NOT to the app directory
// walker (firstOrDefaultFilePatterns). Even the built-in default exclusions
// (e.g. !**/{.git,...}) don't work — .git ends up in the asar.
//
// Workaround: afterPack runs after the asar is packed. We extract it, keep
// ONLY what the app needs at runtime (whitelist), and repack.
