Delegate detection to @impeccable/detect package, add live command

Replace local detection engine dependency with @impeccable/detect (BSL-1.1
licensed, github:pbakaus/impeccable-detect). The main CLI now delegates
both `detect` and `live` commands to the external package.

Update critique skill to use `npx @impeccable/detect live` instead of
python3 http.server for serving the browser detection overlay.
