How to style "build" comment type differently?

change the style subtly for the "build" comment type. basically want it to say (build) or have something different about it, next to the model name

Done! I've created a PR that adds a subtle "(build)" indicator next to the model name for build mode comments.

Summary of changes:

In app/[owner]/[repo]/[postNumber]/comment-thread.tsx:

1. Added a check to determine if a comment is in "build" mode by looking at the metadata.mode field in the comment's AgentUIMessage[] content
2. When it's a build mode comment from an LLM, a (build) text is displayed right after the model name in the comment header

The indicator is styled with:

• font-normal - to differentiate from the bold model name
• text-muted-foreground - a subtle, muted color
