bump version to 3.8.6+112

When a file is converted externally (e.g. FLAC to OPUS), the
orphan cleanup would delete the history entry because the original
path no longer exists. Now it checks for sibling files with other
audio extensions and updates the stored path instead of deleting.

Also add extension-stripped keys to path_match_keys so that
paths differing only by audio extension still match during local
library scan exclusion and queue deduplication.

 ## 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.
+
 **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 is download not working in my country?**
