I would prefer the old-school approach to wrapping the "Claude bits" in a per-platform framework (or if you really can't be bothered, a platform-specific command-line tool that could then be called natively from the program). The UI wrapper then could be Electron, or something a little more platform-native you hand off to some junior engineers.
