stupid-app v0.0.19 for Apple Silicon macOS

stupid-app 0.0.19

Adds an optional deviceFamily key to stupid-app.yml (iphone | ipad | universal,
default universal) that sets the UIDeviceFamily written into the synthesized Info.plist
for the app and every bundled extension. An iPhone-only app also omits the iPad orientation
key, so iPadOS and Apple silicon Mac present the phone layout instead of a resizable iPad
layout. Unsupported values are rejected loudly.

No command, option, default, or output path changed.
