wcc/ww: chained-index str/slice element loads the full header

Browse Source 
cgindex read one word for a str/slice ELEMENT of a chained index
(xs[i][j], f().s[i]) — the element-kind gate keyed on node shape and
missed non-simple bases, dropping the 24B/16B header load (review
finding #22). Key on the element-type stamp; 989_chainidx_run pins
cs==ww (red 3/8 pre-fix).
