Walks the list; if the head appears in the tail (membero), drop it and recurse; otherwise keep it and recurse. Result preserves only the *last* occurrence of each value. Caveat: with input like (1 1 1) the membero check succeeds with multiplicity, so multiple (1) answers may emerge — each is shape- identical, but the test deliberately checks every-result-is-(1) rather than asserting answer count. 5 new tests, 526/526 cumulative.
