type returns the JVM class (Clojure semantics) (#244)

Browse source 
(type x) was jolt's internal taxonomy keyword (:string/:set/:jolt/inst), which
breaks any library dispatching a multimethod on [(type a) (type b)] against
java/clojure.lang classes (e.g. clojure.tools.logging.test's matchers). Make the
PUBLIC clojure.core/type Clojure's (or (:type meta) (class x)).

The taxonomy keyword stays the core model: natives-meta.ss keeps jolt-type and
exposes it as __type-tag, which print-method/print-dup dispatch on (so #uuid/#regex/
records still print). The JVM mapping lives in the java host layer — host-class.ss
defines the public type next to (class …), and a jinst now reports java.util.Date
(was :jolt/inst). So the core emits the taxonomy and the java layer remaps it in one
place. unit.edn's type suite updated to the class names. make test green.
