Subject: [PATCH] fix(fzf): drop focus/resize bind entirely on older fzf builds

Older fzf (pre-0.62) does not support the focus and resize events in
bind actions, causing a startup error when --fish or the bundled
integration is sourced. Split the FZF_DEFAULT_OPTS preview block into
an if/else: newer fzf gets the dynamic bg-transform bind with wrap-word;
older fzf gets a static preview window with plain wrap and no event bind.
