Personal agent teardowns

One page per product. Each covers the same five axes, so the columns are comparable.

• PinePhones companies on your behalf about bills, refunds and cancellations.
• InstinctLives in your messaging apps rather than in a new interface.
• MuseMeta's personal agent, with a Linux machine of your own behind it.
• TownWeb and native Mac, with a real foothold on the machine itself.
