build(mobile): automate App Store metadata

[AprilNEA]

What changed

• add version-controlled English and Simplified Chinese App Store metadata
• configure the production iOS submit profile to use store.config.json
• add an independent manual GitHub Actions workflow that validates and publishes metadata without rebuilding the apps
• ignore local EAS credential manifests

Why

App Store listing changes need a reviewable and independently retryable release path. Publishing metadata separately avoids rebuilding signed iOS and Android artifacts for copy-only updates.

Impact

Maintainers can run Publish Mobile Metadata from GitHub Actions. The workflow uses the protected release environment, its existing EXPO_TOKEN, and the App Store Connect API key stored by EAS.

Validation

• actionlint .github/workflows/build-mobile.yml .github/workflows/publish-mobile-metadata.yml
• eas metadata:lint --profile production
• pnpm check:ci
• pnpm test — 302 files passed, 3 skipped; 2435 tests passed, 5 skipped

Serialize metadata publishing with mobile submissions

When this workflow is dispatched while build-mobile.yml is running with submit: true, the workflows use different concurrency groups (publish-mobile-metadata versus build-mobile-production) even though the iOS submit profile now has metadataPath and the build workflow invokes eas submit --profile production. A metadata-only run from a newer ref can therefore publish first and then be overwritten by the older build run when its long native build finishes; use a shared concurrency group for both App Store writers or stop the artifact submission path from uploading metadata.
