Subject: [PATCH] Log unhandled errors and promise rejections in the desktop
 app

Test code:

    setTimeout(() => testFunctionSync(), 5000);
    setTimeout(
        () => testFunction().then(() => console.log("done testFunction")),
        10000,
    );

    const testFunctionSync = () => {
        console.log("sleeping not");
        throw new Error("Handle me");
    };

    const testFunction = async () => {
        console.log("sleeping");
        await fs.mkdir("/tmp/foo", { recursive: true });
        console.log("woke up");
        throw new Error("Handle me");
    };
