/**
 * E2E smoke tests for the dev-mode desktop app.
 *
 * These tests launch the Electron app from the built dist/ (not the
 * packaged binary) with a real `hermes serve` backend pointed at a mock
 * inference server. The full chain is exercised:
 *
 *   electron → hermes serve (python) → mock provider → renderer
 *
 * Prerequisite: `npm run build` must have been run so dist/ exists.
 * Run from the nix devshell:
 *   npm exec playwright test e2e/boot.spec.ts --reporter=list
