The operator parts of the persistence and config-changes pages merge into
agents/persistence.md. The sqlite tables, state dirs, mounts and migrations move
to 4-implementation/agent-state/persistence.md, and the deploy path, meta flake,
deploy markers, startup migrations, root container, system messages and
autoupdate move to 4-implementation/agent-state/config-changes.md. Links, code
comments and nix comments that named the old sections point at the new pages.
The controller's status, queue, AGENTS.md and forge-webhook details move to
4-implementation/swarm/controller.md. The metrics, logs and OTEL detail moves to
4-implementation/swarm/telemetry.md. Each leaves a short operator blurb with the
options to touch, and links into the moved text are updated.
