A viewer opened from a foot shell (zathura/imv, incl. from mc) now hides the terminal and takes its place, restoring it on close. Requires standalone foot: server/client mode shares one process across all windows, so PID-based swallow cannot tell them apart. `$mod+Return` runs `foot`, not `footclient`, and the `foot --server` exec-once is dropped.
