refactor: extract asar from electron-builder output instead of custom script

scripts/build-asar.js

-/**
- * 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.
- *
- * Automatically resolves transitive dependencies so sub-deps are never missed.
- *
- * Usage:
- *   npm run build:asar                     # default (github) update source
- *   UPDATE_SOURCE=gitea npm run build:asar  # gitea update source
