chore: bump version to 4.1.3 (build 120)

- Fix M4A/ALAC scan silently failing on Samsung by adding proper fallback
  to scanFromFilename when ReadM4ATags fails (consistent with MP3/FLAC/Ogg)
- Propagate displayNameHint to all format scanners so fd numbers (214, 207)
  no longer appear as track names when /proc/self/fd/ paths are used
- Cache /proc/self/fd/ readability in Kotlin to skip failed attempts after
  first failure, reducing error log noise and improving scan speed on Samsung
- Fix Qobuz download returning wrong album cover when track exists on
  multiple albums by preferring req.CoverURL over API default
- Fix FFmpeg M4A metadata save failing with 'codec not currently supported
  in container' by forcing mp4 muxer instead of ipod when cover art present
- Clean up FLAC SAF temp file after metadata write-back (was leaking)
- Update LRC lyrics tag to credit Paxsenix API
- Remove log message truncation, defer to UI preview truncation instead

 ## Extensions
 
-Extensions allow the community to add new music sources and features without waiting for app updates. When a streaming service API changes or a new source becomes available, extensions can be updated independently.
+Extensions let the community add new music sources and features without waiting for app updates. When a streaming service API changes or a new source becomes available, extensions can be updated independently.
 
 ### Installing Extensions

-2. When opening the Store for the first time, you will be asked to enter an **Extension Repository URL**
+
+1. Open the **Store** tab in the app
+2. On first launch, enter an **Extension Repository URL** when prompted
 3. Browse and install extensions with one tap
 4. Or download a `.spotiflac-ext` file and install manually via **Settings > Extensions**
 5. Configure extension settings if needed
-6. Set provider priority in **Settings > Extensions > Provider Priority**

 ## FAQ
 
-**Q: Why does the Store tab ask me to enter a URL?**  
-A: 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.
+<details>
+<summary><b>Why does the Store tab ask me to enter a URL?</b></summary>
+<br>
 
-**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.

-**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.
+</details>
 
-**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>
+<summary><b>Why is my download failing with "Song not found"?</b></summary>
+<br>
 
-**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.
+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: 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).
+</details>
 
-**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.
