Description

The agent holds a file called wazuh-agent.state containing data related to the connection. We expect this file to disappear at the agent's stop.

This PR aims to fix this behavior in the Windows agent, that was not deleting the file properly.

Added

• test_state_delete at test_agent_delete.
