Let the iOS project open and run in Xcode straight from a clone.

The build script now extracts content.json into derived data and copies
it into the app bundle, so no generated file is referenced from the
project or written into the repository. Signing is explicit: ad hoc for
the simulator, automatic with your own team for a device.
