Desktop app (macOS): restore the copy button on the file pane

What happened

In the Claude desktop app's Code tab on macOS, the file pane, where files attached in the chat
are previewed, had a copy button that put the file's raw contents on the clipboard. That
button is gone. To paste a markdown file into another app, I now have to ask Claude to run
pbcopy for me, or open the file in a separate editor and select it there.

What I want

Put the copy button back on the file pane: one click, raw file contents on the clipboard.

My position

I am aware this was an intentional change, and I see it as a deliberate removal of my agency.
The copy button let me act on my own files myself. Without it, a one-click task I used to do
on my own now has to go through the AI as a request. Turning a direct user action into a
request to the model takes control away from the user, and I object to it.
