Lead with what is scarce, not with the mechanism (#10)

The opening line began "Give an agent a computer of its own" and then listed
parts. It read as a how-to rather than a claim, and it was weaker than both the
GitHub About and the paragraph six lines below it, which is a bad trade for the
first thing a stranger reads.

Everyone has agents now. What is scarce is one you would give real credentials
to, so the line says that first and spends the rest on why it is safe.

The paragraph underneath opened with the same teammate-and-own-computer framing
and repeated it almost verbatim. It now carries what the opening cannot: bring
any agent, watch it, take the wheel, components, your own machine.
