xcodegen 2.45.4 does not generate a "TabataGo" scheme (only
RevenueCatUI, RevenueCatUITests, TabataGoUITests). The -scheme flag
therefore fails. Reverting to -target TabataGo as was previously used.
Verified: all .accessoryCorner usages in TabataGoComplication.swift are
properly guarded with #if canImport(WatchKit), so the watch target
transitive dependency build will not surface accessoryCorner issues.
