[Bug] VSCode Sidebar Copy Includes Unwanted Layout Whitespace

<img width="2012" height="1030" alt="Image" src="https://github.com/user-attachments/assets/a14a44b8-0151-426b-98ef-ef81d2029f3c" />

Bug Description
Copying text from the Claude Code VSCode sidebar panel includes trailing whitespace (visual padding from the rendered layout). The same content copied from VSCode's integrated terminal is clean. Padding should be stripped before reaching the clipboard. Reproduces every time on macOS / latest VSCode / latest Claude Code extension.
