feat: ship zoom chords unbound — they live in input.kdl now

Remove the three compiled-in zoom defaults (zoom_in
super+ctrl+shift+equal, zoom_out super+ctrl+minus, zoom_reset
super+ctrl+equal) from DEFAULT_BINDINGS; the user's input.kdl
cce-window-manager domain carries them instead, per the general
direction of keeping chord assignments in config rather than code.
