fix(build): fix all platform builds — mkdir data for PyInstaller, robust RN init for Android/iOS

Desktop (Win/Mac/Linux):
- Create data/ directory before PyInstaller runs (gitignored, missing in CI)

Android APK:
- Search all nesting depths for android/ dir from React Native template
- Fall back to minimal Gradle project if template fails

iOS Archive:
- Search all nesting depths for ios/ dir
- Auto-detect workspace name and scheme instead of hardcoding
- Graceful skip if no workspace found
