The macOS Developer ID DMG path is green (signed + notarized + stapled). The
iOS/TestFlight step (already best-effort + continue-on-error) was failing on
this runner with 'iOS 26.5 is not installed' — the iOS platform SDK is a
separate Xcode component that isn't installed. Guard the step on
`xcodebuild -showsdks | grep iphoneos` and exit 0 with a warning when it's
missing, so runs are unambiguously green. Install on the runner with
`xcodebuild -downloadPlatform iOS` when iOS goes live.
