RAG action gets unchecked on save, if use agent as assistant not selected.

Reviewed the MR and tested the changes. Even after applying the changes, the Enable RAG checkbox will be disabled on each edit , if no agent is selected.

Kindly check again

Before moving forward with the fix, I want to confirm if the RAG Search dependency on agent selection in AiAssistantForm expected behavior?

In this code

if ($form_state->get('agents_enabled') || $form_state->getValue('ai_agent')) {
  // ... other agent logic ...
  if ($form_state->getValue('enable_rag')) {
    $tools['ai_search:rag_search'] = TRUE;
    $tool_usage_limits['ai_search:rag_search'] = [
      // RAG settings
    ];
  }
}

RAG functionality is only applied when: The ai_agents module is enabled and an ai_agent is selected in the "Use agent as assistant" field. As a result, if no agent is selected or the ai_agents module is disabled, enabling the "Enable RAG" checkbox and configuring RAG settings has no effect, as the ai_search:rag_search tool is not added to tools or tool_usage_limits. Is this dependency on agent selection the expected behavior for RAG functionality? Or should RAG be available independently when the ai_search module is enabled and the "Enable RAG" checkbox is checked?

If so, I’m considering moving the RAG logic outside the agent condition, placing it within the existing if ($this->moduleHandler->moduleExists('ai_search')) block in submitForm. This would allow RAG to function independently of agent selection.
