FE-1506: Show captures and completion while a panel elicitation runs

[lunelson]

🌟 What is the purpose of this PR?

The first human elicitation from the Petrinaut panel (FE-1503) needs the person at the panel to see what the interviewer has captured and whether the interview is complete while it runs. This branch surfaces capture and completion facts in the sweep results, keeps their presentation in the Petrinaut host, and states the attach contract between Petrinaut and the Brunch server.

Draft: opened so the stack is visible end to end. The description is completed when the branch is tied off.

PR Summary

Low Risk
Demo-app transport decoration and richer sweep payloads; no auth or persistence changes, with behavior locked by harness and transport tests.

Overview
Sweep tool results now carry the full capture list (with derived active/superseded/retracted status) and the completion report, so panel users can see what was elicited and what still blocks completion while the interview runs.

The local-storage demo wraps the chat transport with createBrunchPanelTransport, which intercepts brunch_sweep stream chunks and merges human-readable title, detail, and items onto the raw output (refused, no-settled-range, and applied paths). SWEEP_TOOL_NAME is exported from transport-aisdk for that hook.

Tests and docs follow: the baseline harness test asserts captures, evidence, and completion failures on the applied sweep part in message history; a Vitest covers the transport decorator; petrinaut-integration.md adds the stable attach contract (chat stream, brunch_ask, principal header) and related wording; user-facing assistant docs mention inline sweep cards.
