Each service section lost its container, credential and metrics detail to a
Host setup section on its own implementation page, unchanged apart from links.
The four agentAuth option rows that sat above the page title moved into the
telemetry page's metrics option table.
The queue subjects, scratch directory and stdio steps of a login, the harness's
newer-version rule, the minter's grants, the caveat and the metrics move to
4-implementation/swarm/claude-login.md. The handbook page keeps how to log an agent
in, the stored login and who may do it. Design pointers in the nix module, the
crate README and AGENTS.md name the new page.
