// electron-updater 6.8.9 resolves the Mac download when its local HTTP response
// finishes, before Squirrel validates/extracts the ZIP. Wait for native ready
// instead, and never arm a future quit from a premature Restart request.
// Exact, single-site replacements deliberately fail closed on upstream changes.
