rand-nth follows the reference shape; refresh doc counts and the corpus floor

Browse source 
rand-nth vec'd its argument, so (rand-nth nil) hit index-out-of-bounds
through the empty vector where the reference's (nth coll (rand-int (count
coll))) returns nil (and a set throws) — the last genuinely-fixable row in
the suite baseline; rand-nth is fully clean now. Corpus/README counts
updated to the current ~3570 rows, the run-corpus regression floor raised
from 2730 to 3390 to match current parity, and the stale traceability line
dropped.
