Hi, this is my first contribution to the CNCF Glossary project.

I’ve implemented a client-side Glossary Assistant chatbot that allows users to search glossary terms interactively.

Happy to make any changes or improvements based on feedback. Thanks!

I’ve added a brief overview before displaying the results to provide quick context. I also structured the output to highlight the top glossary match separately and organized related matches below, while removing duplicate entries.

Would appreciate your feedback on the updated behavior.

Hello @sudheerr937-ai, thank you for your effort; however, as noted in #3624, the glossary maintainers do not feel we need a chat bot on the glossary.
