Problem
When copying a screenshot from WeChat (微信截图) and pressing Ctrl+V in Crush's chat editor, the image is not attached. Pasting a copied image file works fine.
Root cause
Crush reads clipboard images through github.com/aymanbagabas/go-nativeclipboard. On macOS, that library only reads NSPasteboardTypePNG:
// github.com/aymanbagabas/go-nativeclipboard/clipboard_darwin.go
case Image:
pasteboardType = NSPasteboardTypePNGWeChat screenshots are copied to the pasteboard as NSPasteboardTypeTIFF (or other bitmap representations), not PNG. Because the PNG type is absent, nativeclipboard.Image.Read() returns ErrUnavailable, and Crush falls back to reading text from the clipboard, which is empty or not a path.
Expected behavior
Crush should accept common clipboard image representations on macOS (PNG, TIFF, JPEG, etc.) and convert them to a supported image attachment format, similar to how other CLI tools like Codex handle screenshot paste.
