// Subscribe
const unsubscribe = eventBus.subscribe('session-output', 'session-123', (data) => {
  console.log(data.content);
});

Key Methods:

• addConnection(sessionId, res, req) - Add SSE connection
• sendEvent(sessionId, res, data) - Send event to client
• broadcastToSession(sessionId, data) - Broadcast to all clients
• getConnectionCount(sessionId) - Get connection count
• getStats() - Get connection statistics

Usage:

const sseManager = require('./services/sse-manager');

// In route handler
app.get('/api/session/:sessionId/events', (req, res) => {
  sseManager.addConnection(req.params.sessionId, res, req);
});
