Close the remaining Phase-2 stdlib parity gaps. clojure.set: pure Clojure over core, so just added to the prelude stdlib tier (driver.janet stdlib-ns-files + jolt-chez fingerprint), same as clojure.edn. clojure.math: not a .clj on the seed (native math/ bindings via jolt-h79), so Chez gets its own host/chez/math.ss def-var!ing each fn over Chez native flonum math. The analyzer already knows the ns (api.janet install-clojure-math!), so refs lower to var-deref. Also adds the missing 'long' coercion to converters.ss (int's sibling; several math cases wrap in long). clojure.pprint: dropped the 2-arity's (binding [*out* writer] ...). *out* isn't a bindable var in jolt — printing routes through the host (dyn :out) seam, so the binding never redirected anything; it only made the defn uncompilable, which the seed tolerated via interpreter fallback. Chez has no fallback, so the whole pprint defn died. Dropping it is behavior-preserving (writer was always ignored) and lets pprint compile cleanly. Both corpus cases pass. Corpus parity 2259 -> 2280, crashes 191 -> 170, 0 new divergences. Floor raised. New unit test test/chez/_stdlib.janet (27/27). Full Janet gate green (147 files).

|
;; clojure.math fn, over Chez's native procedures. The analyzer already knows the
|
|
