Subject: [PATCH] fix: turn off remain-on-exit only on fzf-tmux pane

Using `fzf-tmux` overwrites `remain-on-exit` for all panes in a window,
if it is only set globally or at a higher scope than window.

	set-option -wg remain-on-exit on
	set-option -s remain-on-exit on

This makes other panes in that window close immediately on exit after
using `fzf-tmux`, even though I expect them to remain open.

Since TMux 3.0, `remain-on-exit` is a pane option that can be set via
`set-option -p`. This will limit the option's scope to just the
`fzf-tmux` pane, thus allowing us to close it immediately without
overriding `remain-on-exit` on other panes in the window.
