Switch agent-team-status.service ExecStart from status_page.serve to
dashboard.serve (uvicorn serving web/dist + the JSON API). Document the WebUI in
the README: live auto-laid pipeline map, click-through task history, endpoints,
and the Mac-side npm build + rsync flow.
The README still described 'FOUNDATION modules only — no coordinator, no transports, no CI workflow'. Updated to reflect the built+merged pipeline (P1 human gate, P2 planner+review, live coordinator+transports+intake, P3-inert build/verify subgraph, P4) with the current layout, the pipeline diagram, key design points, and the deploy-gated/not-built items (P3 live CI, provisioning).
