fix: create XDG state dir for chpwd recent dirs

The chpwd_recent_dirs handler errors when $XDG_STATE_HOME/zsh/
doesn't exist. Add a mkdir -p guard before setting the zstyle.

Also rewrites za() to properly handle zellij list-sessions output
by splitting into a zsh array and filtering empty lines. Adds a
$ZELLIJ nesting guard and passes explicit session name to attach.
