- Convert never removes a path that is the preview it just wrote. It
compares the device and inode, or the resolved and normcased paths when
the disk has no inode numbers. This covers x_thumb.JPG on a
case-insensitive disk.
- A JPEG XL encode failure re-runs encoder detection only when the
encoder's binary or module is gone. A "no encoder" result is checked
again on the settings read, on a jxl save, and after 60 s, so one slow
probe no longer turns JPEG XL off until a restart.
- The startup sweep now also removes temp files that carry this process's
PID but predate its start. Containers reuse PIDs.
