[mdciri]

List of Changes

Update the tool description and function to generate smart chips.
Update the react prompt in order to not have the list of reference twice in the final answer.

Motivation and Context

the smart chips should only be generated when both rag tools are used and they both return relevant information for the user's query.

How Has This Been Tested?

Locally in docker composer

Pull request overview

This PR adjusts the “smart chips” (follow-up questions) flow so chips are generated only when both DevPortal and Cittadino RAG contexts are available/relevant, and tightens system-prompt guidance around where references may appear.

Changes:

• Add gating logic + stronger instructions for when FollowUpQuestionsTool should be called and when it should return empty output.
• Simplify the Discovery agent run() invocation by removing Context/early_stopping_method arguments.
• Update ReAct system prompt wording to reinforce that references must not be duplicated in the final answer text.
