refactor: registry pattern for jolt-hash + jolt-class (jolt-lmot)

Browse source 
Replace the set!-capture-and-rebind chains extending jolt-hash (3 sites: inst-time/
host-table/records) and jolt-class (3 sites: bigdec/natives-queue/host-table) with a
register-hash-arm! / register-class-arm! registry (the pattern already used by
register-str-render!). The base dispatcher walks its arms — disjoint types, so order
is immaterial — then falls to the base cases. The entry is stable, so the per-site
(def-var! "clojure.core" "class" …) re-points are gone.

Behaviour-preserving (runtime .ss, no re-mint): jinst hash, bigdec/queue/record
class, record hash, and a sorted-map hashing as its plain map all verified; make test
green, 0 new corpus divergences. First two of six dispatchers; get/=/pr-str follow.
