tmuxrdr: tmux-mode plugin

The tmux default prefix bindings herdr has no built-in action for, as a
herdr plugin built on its CLI and socket: break-pane, swap-pane and
rotate-window by pane order (focus behaviour measured on tmux 3.7c),
mark/clear-mark, last-window and switch-client -l (from focus events, per
session), select-window and move-window by index, paste-buffer -p,
display-message in tmux's default format, select-layout -E, kill-pane and
kill-window behind tmux's y/n prompts, a command prompt taking tmux's
commands, clock-mode, show-messages, and automatic-rename.

Also a .gitignore for secrets scoped to tmuxrdr/, leaving herdr's own
untouched.
