cycle: one root, once — a verse that repeats a word (tablet 32a)

Reading roots from the verse (tablet 32) met a verse that carries אור
twice: the real engine answers per word and Bereishit 1:3 came back
with א-ו-ר listed twice, each already carrying positions 4 and 6.
uniq_by shoresh after normalization. Found by running the built image
against the real shoresh-engine binary, not by the suite.
