PR visual overview

A fresh agent reads one pull request and draws what it does as one self-contained HTML page with Architecture and UI/UX tabs. The page has no findings. Pair it with whatever review reports the problems. The agent sees only the PR, never this session.

1. Ask which model and reasoning effort should write the overview. Offer only models this runtime can launch as a fresh agent. No default.
2. Launch one fresh agent on that model with no history: the Agent tool with general-purpose in Claude Code, spawn_agent with fork_turns: "none" in Codex, or delegate_task in T3 Code. Give it only the PR URL, the path of references/writer-brief.md, and the output folder printed by node <skill-dir>/scripts/overviews.mjs path.
3. Reply with the page path.
