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.

+ * Restore Local Capacitor Plugins
+ * 
+ * This script ensures that local custom plugins (SafeArea and SharedImage)
+ * are present in capacitor.plugins.json after `npx cap sync` runs.
+ * 
+ * The capacitor.plugins.json file is auto-generated by Capacitor and gets
+ * overwritten during sync, so we need to restore our local plugins.
+ * 
+ * Usage:
+ *   node scripts/restore-local-plugins.js
+ * 
+ * This should be run after `npx cap sync android` or `npx cap sync ios`
