tisfeng/Easydict ? reverse-engineered prompt

Build me a polished macOS dictionary and translation app like Easydict, something that feels clean, fast, and easy to use right away.

I want the app to let me look up words or translate text from the keyboard, from selected text, and from screenshots with OCR. It should automatically detect the language, support a small floating lookup experience, and copy OCR text to the clipboard when I use the silent capture mode. Please include support for multiple translation and dictionary sources, like Apple Dictionary, Apple Translate, and a few online services, with the ability to show results from more than one source at once.

Make it feel native to macOS, with a simple elegant UI, sensible default shortcuts, and good error handling when a service is unavailable. If anything is unclear, check the current docs online before guessing.
