[FEATURE] VSCode Extension: Support for click on @-mentions / code references

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

You can add @-mentions / code references to the chat input:

<img width="447" height="110" alt="Image" src="https://github.com/user-attachments/assets/32aa9aea-d7d7-47ce-b2a1-f088b377f425" />

But there is no way to "interact" with it (e.g. click on it). Which makes opening code mentions a bit more "involved". Cursor's chat input has this and it makes the UX much better.

Proposed Solution

One should be able to click on @-mentions / code references / links generally and this should trigger the default vscode action (e.g. open the file and scroll to the referenced line etc.).
