[floydkim]

Background

This PR migrates our E2E execution path to maestro-runner and improves the RN/Expo matrix runner workflows for better operability and reporting.

What Changed

E2E runner migration and iOS Team ID handling

• Updated e2e/run.ts to run flows via maestro-runner.
• Added --team-id CLI option.
• Added iOS Team ID resolver and tests.
• iOS Team ID handling is included to satisfy maestro-runner requirements for iOS WDA signing.
• Added maestro-runner report output handling and ignored artifacts:
  • e2e/reports/
  • drivers
• Added Android Gradle daemon cleanup (./gradlew --stop) after builds and E2E runs.

RN CLI matrix runner improvements

• Extended scripts/e2e/run-rn-cli-matrix.sh with:
  • --maestro-only
  • --only-setup
  • --legacy-arch-max-version

Expo matrix runner improvements

• Extended scripts/e2e/run-expo-matrix.sh with --only android|ios.
• Added per-target pass/fail tracking and final summary output.

Setup script updates

• Updated scripts/setupExampleApp/runSetupExampleApp.ts:
  • Added --disable-new-architecture.
  • Supports both default behavior (legacy for < 0.77) and explicit override.

Docs and workflow updates

• Updated E2E docs to reflect maestro-runner usage:
  • e2e/README.md
• Added matrix runner docs:
  • scripts/e2e/README.md
• Updated manual E2E workflow to install maestro-runner:
  • .github/workflows/e2e-manual.yml

Scope

• No production runtime behavior changes.
• Changes are focused on E2E tooling, scripts, CI workflow, and documentation.
