  "summary": "Successfully implemented server-side SSE events for agent lifecycle. Extended the dashboard's SSE endpoint (/api/events) to emit agent lifecycle events from AgentStore. Key changes:\n\n1. Server (server.ts): Added shared AgentStore instance with lazy initialization to avoid breaking test environments. The store is initialized only when agent routes are accessed.\n\n2. SSE Handler (sse.ts): Extended createSSE() to accept optional AgentStore and listen to agent:created, agent:updated, agent:deleted, and agent:heartbeat events. Events are emitted in the same format as task events with proper cleanup on connection close.\n\n3. Routes (routes.ts): Updated createApiRoutes() signature to accept optional AgentStore and modified all agent routes to use the shared store via a getAgentStore() helper.\n\nBuild passes and all relevant tests pass (340 core, 604 engine, 268 dashboard server-side). Pre-existing SubtaskBreakdownModal test failures are unrelated to this change."
