Subject: feat(hyprland): rebind mod+shift+f to allfloat, add chess setup
 script

Add workspace allfloat toggle on mod+shift+f (was togglefloating, now
on mod+shift+space only). Add scripts/setup-chess.sh for En Croissant,
lc0, Maia, and Stockfish setup. Update log-cleanup to use filename
dates instead of mtime. Update ssh and calibre configs.
