Parent issue:

• Add support for agent self-restarting for Linux #77

Description

Develop unit tests to validate the agent's ability to recognize and process the self-restart command. (Reference issue #77 for considerations on updating any broken unit tests.)

Tasks

• Develop and execute unit tests for the new functionality.
• Update the unit-test that was broken by the implementation
• Perform integration tests to ensure the command works across different environments.

• I started working on this and researched the argument implementation used to recognize the command and arguments for starting the Wazuh agent service, causing some unit tests to break.
