scripts: add cleanup-i3 and cleanup-sway uninstallers

Browse Source 
Two POSIX sh scripts to undo a session install on a Void host: remove
session-exclusive packages (filtered to those actually installed),
exclusive dotfiles and runtime state, plus the emptty session entry.
Shared resources (dunst, rofi, alacritty, xfce4-screenshooter) are left
in place so the other session keeps working. Confirmation prompt before
any destructive action.
