What to do next

TODO: this page will give new users a short list of high-value first actions: ask the assistant about a recent meeting, search a contact, run a "follow up with" digest, set up the morning brief, plug in WhatsApp, plug in Apple Mail.

Owner: @andy. Aim for 5 to 7 concrete things a user can try in the first 30 minutes. Cross-reference the demo script and the Marvin tools list.
