## 🐛 Describe the Bug

Sonar-Deep-Research shows the same source/url as if they were different sources in search\_results.

## ✅ Expected Behavior

Each source should be unique and not appear duplicated.

## ❌ Actual Behavior

search\_results sometimes shows the same url/source more than once, as if they were different sources.

## 🔄 Steps to Reproduce

1. Call the API with the contents shown below.
2. Sometimes the search\_results object will have duplicated values of sources/url. It doesn’t happen everytime, and I couldn’t find the reason why, since the request is always the same.
