Export universe run as shareable JSON (replay mode)

[Dhwanil25]

Overview

Allow users to export a completed Agent Universe run as a self-contained JSON file that can be:

• Shared with teammates
• Replayed in Agentis to step through the agent execution visually
• Used as a debugging artifact

Export format (proposed)

{
  "version": "0.2.0",
  "task": "Research competitive landscape for AI coding tools",
  "exportedAt": "2026-03-22T10:00:00Z",
  "agents": [ { "id": "...", "name": "Researcher", "provider": "anthropic", "modelLabel": "claude-sonnet-4-6", "role": "researcher", "output": "..." } ],
  "messages": [ { "fromId": "orchestrator", "toId": "agent-1", "content": "Deploy Researcher", "ts": 1234 } ],
  "finalOutput": "...",
  "durationMs": 42000
}

Implementation

• Add Export Run button to the post-analysis panel in UniversePage.tsx
• Add Import & Replay button on the Universe landing view
• Replay mode: feed the JSON into state directly, animate the canvas at 2× speed stepping through messages by timestamp
