Summary

Add a web-based dashboard (bernstein live --web) that shows real-time agent status, task progress, bulletin messages, and metrics.

Motivation

The CLI bernstein live command works but a browser dashboard would be more accessible, especially when running longer orchestration sessions.

Proposed features

• Real-time task board (open / in-progress / completed)
• Agent heartbeat status (alive / stale / exited)
• Bulletin board feed
• Metrics charts (tasks/hour, success rate, TTFT)
• Evolution history with before/after diffs
