[Bug] Clipboard copy to system clipboard broken after update

Bug Description

Title

Clipboard copy broke after update — copying no longer reaches the system clipboard (regression)

Body

What happened:
Copying highlighted text from inside Claude Code used to work and now doesn't. When I copy, nothing lands in my clipboard — paste gives nothing or old text. An earlier version worked fine; a recent update broke it.

What I expected:
Highlight + Ctrl+Shift+C copies to my system clipboard, like it did before.

Environment:

• Claude Code version: 2.1.195
• OS: Ubuntu 24.04.4 LTS
• Terminal: GNOME Terminal
• Plain terminal copy still works; only Claude Code's copy is broken.

Fix requested:
Restore working copy out of the box, as it was in earlier versions — no extra tools or configuration should be required. Copying highlighted text should just work.

Environment Info

• Platform: linux
• Terminal: gnome-terminal
• Version: 2.1.193
• Feedback ID: d70d8a45-430f-4d12-912f-fe9417fc09e7
