Phase 12: CLJS ported tests — 4 files, 27 sections, ~120 assertions

- cljs-port-1a.janet (sections 1-6): core math, predicates, comparison,
  vectors, maps, sets — all pass (54 assertions)
- cljs-port-1b.janet (sections 7-11): seq operations, printing, apply,
  higher-order fns — all pass (25 assertions, str nil skipped)
- cljs-port-2.janet (sections 12-15): atoms, special forms, macros,
  constructors — all pass (20 assertions)
- cljs-port-3.janet (sections 16-22): destructuring, set ops, reader
  literals, syntax-quote, walk (skipped), clojure.string, clojure.set
  — 16 assertions pass, walk skipped (needs IFn protocol)
- cljs-port-4.janet (sections 23-27): deftype/defrecord, multimethods,
  protocols, var system, range/into/concat — all pass (15 assertions)

Paren-counting boundary persists in single-file format, split into
separate files is the workaround. 316/317 total (1 pre-existing).
