Make the rice shareable: appearance-only default, --with-shell, --layouts, --restore, 07-input and 99-personal split

- default install: SwayFX + DMS + kitty + fonts/theme + hotkeys/screenshots only
- zsh/tmux/CLI tools behind --with-shell; personal apps/autostart/mouse speed removed from the repo
- keyboard layouts prompt/--layouts, user-editable files (07-input.conf, dms/settings.json) never overwritten
- --restore (oldest backup), unique backup dirs, README rewritten for strangers, private URL removed
