 * The one place that computes the next CFBundleVersion: the highest build of the app over EVERY platform (iOS, macOS,
 * tvOS, visionOS), every processing state and every page, plus one. CFBundleVersion must be unique across the app
 * record's builds, so a platform filter (a macOS build once got a number an uploaded macOS build already had) or a
 * missed page gives a number the store refuses. `apple next-build`, `apple build` and `apple build --platform macos`
 * (also their dry runs) all call this, so they agree.
