macOS: Image paste prompt shows Control+V instead of Command+V, and Command+V doesn't work

Bug Description

When an image is on the clipboard, Claude Code displays a prompt suggesting to press Control + V to paste. On macOS, this should show Command + V (⌘V), following standard macOS conventions.

Additionally, Command + V does not work for pasting images — only Control + V works. This is a dual issue:

1. UI text issue: The hint text shows "Control + V" instead of "Command + V" on macOS
2. Keybinding issue: Command + V (the standard macOS paste shortcut) doesn't actually paste the image — only Control + V does

Expected Behavior

• On macOS, the prompt should display Command + V (or ⌘V)
• Command + V should be the working keybinding for pasting images on macOS

Actual Behavior

• The prompt displays Control + V regardless of platform
• Only Control + V works to paste images, even on macOS
• Command + V does nothing

Environment

• Platform: macOS (MacBook)
• Application: Claude Code CLI
