"""
Test script for the host reconciliation feature.

This script tests the complete reconciliation workflow:
1. Worker connects to WebSocket server
2. Host status moves to 'reconciling'
3. Pod-update tasks are sent for expected containers
4. Reconcile_and_delete task is sent
5. Worker processes the task and deletes unexpected containers
6. Host status moves to 'online' after successful reconciliation
