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).
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.
Add kitty themes and mutt includes loaded by tracked configs, xmonad's stack
build files, new systemd units and overrides, plus picom, pipewire, portal,
modprobed-db, btop, vifm, qt5ct/qt6ct, calcurse, mpDris2 and thefuck configs.
