Development record

`04-surfaces/36-dashboard.md:3` calls the dashboard one of abcd's two network listeners, the other being the brief session relay, and `04-surfaces/37-session.md:14`, `06-delivery/02-verification-matrix.md:25` and `05-internals/03-configuration.md:1914` count the same two. Session set-up opens a third: `LoopbackListener` (`internal/surface/session/appsetup.go:90`, called at `internal/surface/cli/session.go:821`) listens on a loopback port for the forge's answer to the app manifest. The session chapter does not describe it, and the listener boundary test admits two packages rather than two listeners.
