v1.0.1 — Fix SAF content URI access and foreground service type

- SyncEngine now handles content:// URIs via ContentResolver/DocumentsContract
  alongside regular file paths; fixes ENOENT on all SAF-backed sync pairs
- ForegroundInfo now passes FOREGROUND_SERVICE_TYPE_DATA_SYNC on API 29+
- Declare foregroundServiceType=dataSync on WorkManager service in manifest
