Brace group exit code was the last [ -n ] test, which returns 1 when
the variable is empty, triggering || die even on success. Adding true

Replace write to defunct /ctl with s/new spec format. Add -name flag
so named sessions skip the post-write poll. Fix /kill to write to
s/{id}/ctl instead of the removed top-level ctl file.
