feat: Add comprehensive mobile testing infrastructure

- Add test scripts for Android and iOS platforms
- Create prerequisite checker for mobile development setup
- Add device/simulator availability checks
- Update test-all command to include mobile tests
- Add granular test commands for web and mobile

The changes improve testing by:
1. Adding structured mobile test runners
2. Validating development environment setup
3. Separating web and mobile test flows
4. Adding device availability checks
5. Providing detailed test documentation

Added scripts:
- check-prerequisites.js: Validates dev environment
- test-android.js: Runs Android tests
- test-ios.js: Runs iOS tests
- run-available-mobile-tests.js: Smart platform detection
