    scripts/ios-beta-prepare.sh --build-number 7 [--team-id TEAMID]

Prepares local beta-release inputs without touching local signing overrides:
- reads package.json.version and writes apps/ios/build/Version.xcconfig
- writes apps/ios/build/BetaRelease.xcconfig with canonical bundle IDs
- configures the beta build for relay-backed APNs registration
- regenerates apps/ios/OpenClaw.xcodeproj via xcodegen
