Fix Android image share workflow and add local plugin persistence

- Add SafeArea and SharedImage plugins to capacitor.plugins.json
- Create restore-local-plugins.js to persist plugins after cap sync
- Integrate plugin restoration into build scripts
- Improve Android share intent timing with retry logic
- Clean up debug logging while keeping essential error handling
- Add documentation for local plugin management

Fixes issue where SharedImage plugin wasn't recognized, causing
"UNIMPLEMENTED" errors. Image sharing now works correctly on Android.
