Summary

Add pnpm test:desktop and run it in macOS CI. Launch the actual unsigned directory package twice, verify app.isPackaged and its shipped SQLite addon, read persisted data across restart, and confirm both embedded servers close on quit. Isolate Electron profile/config/cache, disable update downloads for the test, and restore/probe the host Node addon after packaging even on failure.

Validation

Local stack head 1d1d925 passed:

• pnpm typecheck, pnpm test (171 unit/integration tests)
• pnpm lint (including four boundary checks), pnpm fmt:check
• pnpm test:e2e (five Chromium scenarios)
• pnpm test:desktop (packaged macOS arm64 launch, restart, SQLite and shutdown)

These are local results; GitHub checks are reported separately.

How to review

Read harness/src/app.desktop.ts, then scripts/desktop-smoke.mjs. The desktop main-process changes only provide profile isolation and an update opt-out. Verified locally on macOS arm64; signing, installer/updater delivery and other platform launches are not covered.

Visuals

First-launch and restart PNGs plus packaged-process diagnostics are attached to desktop-report and the packaged-desktop-feedback CI artifact.
