[BUG] TaskMaster AI Errors Crash Main System

[DonHugo]

Bug Description

Errors in TaskMaster AI component can crash the entire system.

Current Behavior:

• TaskMaster exceptions propagate to main system
• No error isolation
• System goes down completely

Expected Behavior:

• TaskMaster errors isolated
• Main system continues operating
• Errors logged and reported
• Graceful degradation

Impact: High - Full system outage

Required Actions:

• Isolate TaskMaster in try/catch blocks
• Add error boundaries
• Implement fallback behavior (disable TaskMaster if failing)
• Test error scenarios
• Add TaskMaster health monitoring

Acceptance Criteria:

• TaskMaster errors don't crash main system
• Errors properly logged with context
• System continues operating without TaskMaster
• User notified of degradation via MQTT
• Automatic recovery attempts with backoff

Test Scenarios:

• TaskMaster API timeout
• TaskMaster returns invalid data
• TaskMaster process crash
