Cmd+V does not trigger TUI image paste on macOS terminals

[swalker326]

Description

On macOS terminals such as Ghostty, users expect Cmd+V to paste into the opencode TUI. Text paste can be handled by the terminal, but image-only clipboard paste needs opencode's existing prompt.paste command to run so it can read the native clipboard and attach the image.

The default TUI paste binding only includes Ctrl+V, so Cmd+V is not wired to the TUI paste command when the terminal passes that shortcut through.
