New /api/agent-insights endpoint aggregates real data (chat-history,
cost-history, agent-time, agent-registry, router-keywords) to show:
- which agent you chat with most (user turns)
- which agent spends the most time on tasks (derived agent-time)
- which agent is best suited for what (registry desc + router keywords + roles)
- which models you use most per agent (cost-history)
Dashboard page (agent-insights.js) with stat cards, two Chart.js bar
charts, suite cards, models-per-agent table, and full per-agent
breakdown. Verified live in browser against real data.
