What's fixed
Syncthing (and similar sync tools) create hidden dot-folders inside watched directories — .stfolder, .stversions, etc. Bindery was scanning inside them and attempting to convert whatever files it found there.
Changes
- Any directory whose name starts with
.is now skipped universally in both poll and inotify modes — covers.stfolder,.stversions,.archive, and anything else like them
No config changes needed. Existing setups will pick this up automatically on container restart.
