Replace str-render/instance-check set! chains with registries

Browse source 
jolt-str-render-one and instance-check were each extended by a chain of
set!-wrapping closures spread across ~10 and ~5 host files, so the real
behavior of either was scattered and load-order-dependent. Give each a
registry the base file owns: converters.ss/records-interop.ss define the
registry plus a register-* helper, and each extending file registers one arm
instead of capturing %prev and set!-ing the global.

str-render arms are type-disjoint; instance-check arms run newest-first (the
old outermost-wins order) and may return 'pass to defer. The string-token ->
symbol normalization the natives-array arm did for every inner arm moves to
the dispatcher head; array tokens stay strings for that arm to decide.

jolt-ogib.14. Runtime-only shims, no re-mint.
