feat: add flat singles folder option (Artist/song.flac without Singles subfolder)

Load saved registry URL before first state update to prevent brief
flash of the setup screen when the store tab initializes.

Add Ogg/Opus fallback in readFileMetadata when FLAC parsing fails,
handling files saved with .flac extension that contain opus data.

 ## FAQ
 
-**Q: Why is my download failing with "Song not found"?**  
-A: The track may not be available on the streaming services. Try enabling more download services in Settings > Download > Provider Priority, or install additional extensions like Amazon Music from the Store.
+<details>
+<summary><b>Why does the Store tab ask me to enter a URL?</b></summary>
+<br>
 
-**Q: Why are some tracks downloading in lower quality?**  
-A: Quality depends on what's available from the streaming service and extensions. Built-in providers: Tidal offers up to 24-bit/192kHz, Qobuz up to 24-bit/192kHz, and Deezer up to 16-bit/44.1kHz.
+Starting from version 3.8.0, SpotiFLAC uses a decentralized extension repository system extensions are hosted on GitHub repositories rather than a built-in server, so anyone can create and host their own. Enter a repository URL in the Store tab to browse and install extensions.
 
-**Q: Can I download playlists?**  
-A: Yes! Just paste the playlist URL in the search bar. The app will fetch all tracks and queue them for download.
+</details>
 
-**Q: Why do I need to grant storage permission?**  
-A: The app needs permission to save downloaded files to your device. On Android 13+, you may need to grant "All files access" in Settings > Apps > SpotiFLAC > Permissions.
+<details>
+<summary><b>Why is my download failing with "Song not found"?</b></summary>
+<br>
 
-**Q: Is this app safe?**  
-A: Yes, the app is open source and you can verify the code yourself. Each release is scanned with VirusTotal (see badge at top of README).
+The track may not be available on the streaming services. Try enabling more providers under **Settings > Download > Provider Priority**, or install additional extensions like Amazon Music from the Store.
 
-**Q: Why is download not working in my country?**  
-A: Some countries have restricted access to certain streaming service APIs. If downloads are failing, try using a VPN to connect through a different region.
