Problem

Currently we can /include multiple Merge Requests and issues to Duo Chat context, however, Duo Chat backend is organized in a way that it's possible to process only one item. Adding multiple GitLab objects is confusing to users as only one item of the sort will be considered by LLM.

Solution

Allow to select only one issue, one MR per question
