fix: resolve CHANGELOG version mismatch and Android clean hanging issue

- Fix CHANGELOG.md version from [1.0.7] to [1.0.8-beta] to match package.json
- Replace problematic clean:android npm script with robust clean-android.sh script
- Add timeout protection (30s) to prevent adb commands from hanging indefinitely
- Include cross-platform timeout fallback using perl for macOS compatibility
- Improve logging and error handling for Android cleanup process

Fixes team member reported issues:
- CHANGELOG version inconsistency
- clean:android getting stuck during execution
