Retire legacy tmux multi-agent and auto-research demos

demo/README.md

 This directory holds self-contained demos that are kept runnable from the repo
 checkout for reference and experimentation:
 
-- `auto_research/` — the auto-research worker/supervisor showcase (kernels,
-  worker loop, evidence packets, terminal-result query, demo end-to-end).
-- `multi_agent/` — the companion multi-agent launcher showcase (contract,
-  round ledger, role successor, visible launch policy, wake scheduler).
-- `visible_multi_agent_launcher.py` / `visible_multi_agent_tmux.py` — the
-  tmux-based visible multi-agent launcher used by the demo.
+- [`workspace/`](workspace/README.md) — local, repeatable workspace stories
+  backed by isolated LoopX state.
 
 The demos depend on the real LoopX product modules (`loopx.quota`,
 `loopx.todos`, `loopx.status`, …) and are run by importing the `demo` package
 from the repo root (examples and smokes already add the repo root to
 `sys.path`).
 
-These were relocated from the product capability surface
-(`loopx/capabilities/auto_research` and `loopx/control_plane/agents/multi_agent`)
-to make the demo/non-product boundary explicit. If a piece here matures into a
-stable caller contract, it should be promoted back into
-`loopx/capabilities/<capability>/` with a real entrypoint and focused
-validation.
+The retired tmux multi-agent and auto-research prototypes are available in Git
+history. For current collaboration and research examples, see
+[`collaboration-delivery`](../examples/collaboration-delivery/README.md) and
+[`managed-research-team`](../examples/managed-research-team/README.md).
