electron-builder + Vite Packaging Fix

Two separate problems, one config change.

1. The 480MB zip

electron-builder writes to dist/ by default, and so does Vite. Your build.files includes "dist/**/*", so every build packs the
previous build's zips and unpacked apps into app.asar. Nothing errors; it just keeps growing.

electron-builder targets the host architecture. On an Apple Silicon Mac that means an arm64-only app.

Fix

"build": {
  "directories": { "output": "release" },
  "files": ["dist/**/*", "dist-electron/**/*", "!node_modules/**"],
  "mac": { "target": [{ "target": "zip", "arch": ["universal"] }], "artifactName": "App-macOS.${ext}" },
  "win": { "target": [{ "target": "zip", "arch": ["x64"] }], "artifactName": "App-Windows.${ext}" }
}

Add release/ to .gitignore, delete the old artifacts in dist/, and rebuild.

Verify

unzip -l release/App-macOS.zip | grep -E "app\.asar$|\.zip$"
ditto -x -k release/App-macOS.zip /tmp/t && lipo -archs "/tmp/t/App.app/Contents/MacOS/App"
codesign --verify --deep --strict "/tmp/t/App.app"

Expect a small asar with no nested zip, x86_64 arm64, and codesign exiting 0.

Note for your store page

Without an Apple Developer ID the app is ad-hoc signed. Buyers need System Settings > Privacy & Security > Open Anyway on first launch,
so say that on your download page.
