Fixed-arity protocol dispatch shims (#223) 
defprotocol emitted one variadic (fn [this & rest] (protocol-dispatch P m this
(list->cseq rest))) per method, so every protocol call — even a no-extra-arg one
like (area s) — consed a rest list, wrapped it in a cseq, var-deref'd
protocol-dispatch, and jolt-invoke'd it (consing again). On mono-dispatch that was
2.07GB of allocation, ~65% of the benchmark.

Emit one fixed-arity clause per declared arglist instead. The 1/2/3-param arities
call positional protocol-dispatch{1,2,3}, which resolve the impl (by record tag,
reify method, or host-tag extension — factored into protocol-resolve) and apply it
directly; no rest-list, no seq round-trip. The dispatchN entry points are in the
native-op table so the shim calls bind straight to the records.ss procedures
rather than var-deref. 4+ params fall back to the variadic protocol-dispatch.

mono-dispatch 1.5s/2.07GB -> 0.69s/280MB; dispatch 26x -> 12.2x, mono-dispatch
111x -> 51x vs JVM. 5 new corpus rows pin multi-arity methods, host-type args,
and protocol-method-as-value against JVM Clojure.
