Original PR body:

Summary

• Redesigned agentmemory viewer with newsprint-inspired design system (Playfair Display/Lora/Inter typography, CSS variables, responsive layout)
• Added real-time live streaming via iii-engine StreamModule — viewer receives observation events as they happen
• Fixed stream event propagation: engine uses exact group_id matching, so added a dedicated viewer broadcast group
• New tabs: Activity (GitHub-style heatmap + feed), enhanced Graph (curved edges, shapes, legend, search), visual Timeline, improved Dashboard (semantic/procedural memory sections)
• Added standalone viewer HTTP server (src/viewer/server.ts) on port 3113
• New GET /agentmemory/memories endpoint with ?latest=true filter

Technical details

• stream::set with group_id: "viewer" broadcasts to all viewer subscribers (fire-and-forget via triggerVoid)
• Viewer WS subscribes to streamName: "mem-live", groupId: "viewer" and handles create/update event types
• iii-config.yaml adds StreamModule (port 3112), PubSubModule, OtelModule, ExecModule

Test plan

• Start engine: iii --config iii-config.yaml
• Open viewer at http://localhost:3113/agentmemory/viewer
• Verify WS status shows "live" (not "live updates off")
• Create an observation via REST API and verify it appears in real-time
• Check all tabs: Dashboard, Graph, Activity, Timeline, Sessions, Memories, Audit, Profile

Summary by CodeRabbit

• New Features

  • Added a dedicated viewer server with web UI and rich /agentmemory/* APIs for sessions, memories, graphs, profiles, summaries, and governance.
  • New REST endpoint to list memories.
  • Real-time streaming now emits updates for both per-session and viewer groups; viewer server starts/stops with the app.

• Bug Fixes

  • Viewer asset resolution now tries multiple paths and returns clearer not-found responses.

• Chores

  • Added configuration for viewer, telemetry, queuing, cron, streams, and tracing.
