ci(pet): build and verify the Apple app for reviewers

Run the existing Apple checkpoint/PCM workflow on the macOS recorder runner
and upload the locally signed application as a zipped review artifact.
Android keeps its existing separate APK and reports. Neither is a release.

Validation: actionlint pet workflow passed; local macOS packaging/unzip
integrity passed. Product sources are unchanged from ee35326: required
npm test && npm run check:web passed 66 package, 14 SDK, 446 web, 0 failed,
0 web errors and 2 existing warnings. Pet 63/0; Apple 11 workflows + 27
exact PCM ranges, macOS/iOS builds, Watch 12/0, Android 11/0 + APK/lint.
Hosted execution of this new workflow step remains pending.

+The macOS recorder job also runs `check-apple.sh` and uploads the resulting
+locally signed app as `codewhale-pet-macos`. Android uploads its debug APK and
+reports separately. These are CI review artifacts, not notarized releases.

 Apple requires macOS, Xcode command-line tools, and XcodeGen for iOS. The iOS
 script generates and builds the Simulator project directly from the shared
 source, without first building macOS. Open `pet/ios/CodewhalePet.xcodeproj` to run.
