What's Wrong?

Description
In the Claude Code VSCode native extension, I'm unable to paste text into the chat input box. Neither the Ctrl+V keyboard shortcut nor the right-click context menu's "Paste" option (which shows Ctrl+V as its shortcut) inserts clipboard content into the input field.

What Should Happen?

OS: Windows 11 Pro (10.0.26200)
Interface: Claude Code VSCode native extension (chat input box, not the integrated terminal)

Additional Information

1. No conflicting keybindings found in keybindings.json — checked and confirmed no custom binding overrides Ctrl+V.
2. Issue is specific to the chat input box; [add here whether paste works elsewhere in VS Code, e.g. terminal/editor/search box, once confirmed]
