library-dump.timer writes Library-<weekday>.sql.gz to
~/.local/share/library_manager/dumps, which simple_backup then copies;
the login comes from ~/.config/library_manager/dump.cnf (not tracked).
After a successful sync, aurb runs git clean -fx in each clone under the aurutils sync folder, removing downloaded sources and build logs while keeping tracked files and VCS source folders.
vidthumb names thumbnails by a hash of path, size and mtime instead of a jq index that broke on quotes in filenames; systemd-tmpfiles removes ones unused for 30 days. discover-overlay-wait now runs from a systemd user unit started by xmonad and logs to the journal.
.fehbg now saves its random picks to ~/.cache/wallpapers and redraws them with
--keep; screen-layout passes this through with --keep-wallpaper, used by movie.
aurb now builds with clang + lld + ThinLTO and bind-mounts a ThinLTO cache and its clang.cfg into the chroot; --gcc keeps the old gcc build. update-kernel still uses gcc.
