+/**
+ * Build a standalone app.asar + checksums.sha256 for minor (patch) updates.
+ *
+ * Replicates what electron-builder packs into the asar (dist/ + package.json +
+ * required node_modules) without running the full installer build.
+ *
+ * Usage:
+ *   npm run build:asar                     # default (github) update source
+ *   UPDATE_SOURCE=gitea npm run build:asar  # gitea update source
