Feature Request

Summary

Add a live sub-agent mission board to the Control UI dashboard that makes orchestrated agent runs observable in real time.

Motivation

When an orchestrator spawns multiple sub-agents for parallel work, there is currently no way to see what is running, on what model, for how long, or to intervene without dropping to the CLI. This makes orchestration opaque to the user.

Proposed Behavior

• A panel (tab or sidebar section) in the dashboard showing all active sub-agents for the current session
• Per-agent row: label, model tier, elapsed time, status (running / done / failed)
• Kill and steer buttons inline per agent
• Auto-refreshes while agents are running, clears when done

Alternatives Considered

• Polling \subagents list\ via chat commands — works but requires user to ask
• Session list view — exists but doesn't show sub-agent hierarchy or model assignment

Additional Context

The \subagents\ tool already exposes list/steer/kill. This is a UI surface for that existing API.
