Type Alias AppManifestInput

AppManifestInput: Omit<AppManifest, "name" | "tile" | "color"> & {
    color?: string;
    name?: string;
    tile?: AppTile;
}

A manifest as an author writes it, before defineApp fills in the defaults.

Separate from AppManifest for one reason: name is optional here and guaranteed on the way out, so everything downstream can read manifest.name without a fallback.
