<p>The definition of the AiAgent entity does not specify a list_builder handler. Visiting /en/admin/config/ai/agents throws the error: "The "ai_agent" entity type did not specify a list_builder handler."</p>
<p>Current state:<br>
* handlers = {<br>
* "form" = {<br>
* "add" = "Drupal\ai_agents\Form\AiAgentForm",<br>
* "edit" = "Drupal\ai_agents\Form\AiAgentForm",<br>
* },<br>
* },</p>
<p>What we need:<br>
* handlers = {<br>
* "list_builder" = "Drupal\Core\Config\Entity\ConfigEntityListBuilder",<br>
* "form" = {<br>
* "add" = "Drupal\ai_agents\Form\AiAgentForm",<br>
* "edit" = "Drupal\ai_agents\Form\AiAgentForm",<br>
* },<br>
* },</p>
