Copy an entire thread

I would like to be able to copy an entire thread. If that is already possible, I can't find it.

The reason is that in the workflow I'm trying out with Buzz, I'm invoking an agent to discuss issues in a thread. I would like to copy that entire discussion into a separate environment for review (e.g. codex terminal). I understand the goal is not to need to use the codex terminal but I would still find it useful and I'm sure there are other use-cases for copying an entire thread.

The issue does not identify any files, tests, or entry points, so start by locating the thread view and any existing copy or export actions. Done means providing a way to copy an entire discussion into another environment, with the expected copied content and format confirmed by the project.
