[FEATURE]:Add an Alt+V feature to paste images from the clipboard

[W-reverse]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

When using opencode in PowerShell, I tried Win+V, Ctrl+V, Alt+V, and Ctrl+Shift+V, but none of them could paste images from the clipboard. This severely impacts my work efficiency.

I hope to add a feature like Claude Code, where I can use Alt+V to paste images from the clipboard

Well, I guess this is bad timing. I just opened an issue for the same thing, but with more detail, since I talked with the Windows Terminal developers about the default Ctrl+V keybinding, etc: #8490

I also just opened a pull request for it here: #8495

I tested it and it works, it's the best solution in my mind (accept both Ctrl+V and Alt+V for image pasting)
