ExpectUnchanged compares the file's schema ids with the loaded ones, so master's blob (hulls written before
HullData lost GridOffset) made apply throw and write nothing. The batch now expects only that the keys it authors
are absent and lands onto the file as it is. Tests: older-schema replay, the design and maker match, case-insensitive
name conflict, a row name that is a design's, the dispatch word, and the sold-weapon floor replaced by "only Smoke
designs are unsold". LaunchSuppressorCatalogTests reads Program.MakerProfiles instead of spelling six profiles.
Not built or run yet; the catalog blob is regenerated in the next commit.
