Real-time Task Status Updates

User Story

As a user, I want to see real-time updates of my task execution status and logs so that I can monitor progress without refreshing the page.

Technical Requirements

• Implement Server-Sent Events client for real-time updates
• Build task status indicator components with visual feedback
• Create live log streaming interface with auto-scroll
• Add connection state management and reconnection logic
• Implement task progress indicators and execution metrics
• Handle connection failures with user notification

Acceptance Criteria

• Task status updates appear immediately without page refresh
• Log streaming displays output as it generates from containers
• Connection state indicator shows online/offline status
• Automatic reconnection works after network interruptions
• Multiple tasks can be monitored simultaneously
• High-volume log output doesn't freeze the browser

Definition of Done

• Real-time features tested with actual task executions
• Connection resilience verified with network disconnections
• Performance tested with high-frequency status updates
• UI gracefully handles SSE connection failures
• Memory usage optimized for long-running log streams
