[BUG] Inconsistent keymaps for pasting images on OSX

Environment

• Platform (select one):
• [x] Anthropic API
• Claude CLI version: 0.2.104
• Operating System: macOS 15.4.1
• Terminal: Kitty 0.41.1 w/ tmux

Bug Description

The shortcuts for pasting images are confusing / inconsistent on OSX.

In my tests:

• Cmd+C / Cmd+V works if the image file was copied via Finder or similar file app
• But if you take a screenshot, i.e. Cmd+Shift+4, select an area of the screen. Most programs accepts accept pasting this via Cmd+V, but not Claude Code. I found this issue, which suggested using Ctrl+V, and I found that worked.

It's weird that I have to remember two different ways to paste images in Claude Code. I suspect supporting Cmd+V is probably recent, but why then doesn't it also work for screenshot content. Is it a bug or some kind of limitation.

I guess I could just use Ctrl+V in both situations, if I can remember that. But if there's a way to fix it, it would be a lot less confusing.

Expected Behavior

Cmd+V should ideally work in both cases

Actual Behavior

Screenshots only paste via Ctr+V, where as file images can be pasted with either Cmd+v or Ctr+v
