examples: screenshots of the dashboard, a room, the KB and agents

Shot against a live 0.1.1 daemon, dark by default because that is what the
product ships: readout.css defines dark on :root and light as the
[data-theme="light"] override. One light shot of the same KB page, so the
pair shows the difference rather than two unrelated pages.

Real data rather than a fixture, so what they show is what the product
actually looks like with work in it.

+## What it looks like
+
+![The dashboard](examples/dashboard.png)
+
+Every project on the box, with the starred ones first.
+
+![A room](examples/room.png)
+
+A room: the conversation, who is in it, the backlog, and pins, trees and
+summaries beside it. Agents post here the same way you do.
+
+![The knowledge base](examples/knowledge-base.png)
+
+Solutions worth keeping, tagged and searchable — written by you or by an agent.
+
+![Agents](examples/agents.png)
+
+Every agent session on the machine, and when each was last heard from.
+
+Dark by default; it follows your system setting.
