Harden release version wiring

[cbusillo]

Summary

• wait for App Store Connect builds to become visible and VALID before review submission
• harden App Store review/version scans with pagination and READY_FOR_REVIEW handling
• pass the resolved build number through Ship -> Release -> package-native and stamp bundle versions
• preserve explicit App Store build numbers by removing Xcode auto build-number management
• add release workflow/script regression tests

Validation

• python3 -m unittest discover Tests/ScriptsTests
• python3 -m py_compile scripts/submit-app-store-review.py Tests/ScriptsTests/test_submit_app_store_review.py Tests/ScriptsTests/test_release_workflows.py
• shfmt -d scripts/package-native-macos-app.sh scripts/upload-testflight-macos-app.sh
• actionlint .github/workflows/ship.yml .github/workflows/release.yml .github/workflows/submit-app-store-review.yml .github/workflows/testflight.yml
• git diff --check
• swift test

Review

• Claude reviewed the original release workflow issue set and found stale READY_FOR_REVIEW/pagination/build-number risks.
• Gemini/Antigravity independently identified the App Store build-processing race and GitHub Release bundle-stamping gap.
• Claude reviewed the final diff; no blocking issues remained.
