Fix verbose output to show task names instead of UUIDs

- Modified event listener to pass task objects instead of IDs to console formatter
- Updated console formatter methods to display task names with ID fallback
- Added helper method _get_task_display_name with fallback logic:
  1. Task name + partial ID: 'Research Analysis (ID: 12345678...)'
  2. Description + partial ID: 'Analyze market trends... (ID: 12345678...)'
  3. Full ID as final fallback: '12345678-1234-5678-9012-123456789abc'
- Added comprehensive tests for verbose output functionality

Fixes #3310
