fix: expand variadic list + add runtime stubs — 174/233 (74%)

Runtime: cljCompare, cljSubvec, cljRand, cljRandInt, cljRandNth,
cljRandomSample with native Nim implementations
Emitter: expanded variadic function list for correct seq[CljVal] calling

Results: 174/233 passed (74%)
  clojure.string: 8/8 (100%)
  clojure.core: 166/225 (74%)
