Yogthos 6b99591266 Fix [_ _] inline method field binding + Var protocol dispatch 
Two gaps reitit-core surfaced (now 322/0/1 -> 327/0/0):

- A deftype/defrecord inline method with two _ params, (m [_ _] field), read
  the field as nil: mk-clause bound fields off (get _ :field) where _ was the
  first param, but the second _ shadowed it. Each _ param is now renamed to a
  fresh symbol so the instance is unambiguous.

- A var did not dispatch to a protocol's clojure.lang.Var extension (reitit
  extends Expand to Var for a #'handler route): value-host-tags gained a var arm
  (Var/clojure.lang.Var/IDeref/IFn) and host-type-set gained Var/IDeref so the
  extension keys under Var.

deftype/defrecord is a seed source, re-minted.

Chez bootstrap seed

These two files are the bootstrap compiler for jolt — the seed that makes the build self-hosting:

  • prelude.ss — the clojure.core prelude (all tiers + clojure.string/walk/ template/edn/set/pprint) as Scheme def-var! forms.
  • image.ss — the compiler image (jolt.ir + jolt.analyzer + jolt.backend-scheme) as Scheme def-var! forms.

Both are generated, not hand-written. They are checked in because a fresh checkout must be able to build jolt-on-Chez using only Chez: host/chez/bootstrap.ss loads this seed, then rebuilds the prelude + image from the .clj/.ss sources via the on-Chez compiler (read → analyze → emit, all on Chez). The seed is a joint byte-fixpoint: rebuilding from an up-to-date seed reproduces it exactly. make selfhost (host/chez/selfcheck.sh) runs host/chez/bootstrap.ss and diffs the rebuilt artifacts against the checked-in seed.

Re-minting

When the seed sources change (the core tiers, the compiler namespaces, the host contract, the reader, emit-image.ss), the seed drifts and make selfhost fails. Re-mint it by running host/chez/bootstrap.ss and writing the freshly rebuilt prelude/image back to host/chez/seed/prelude.ss / host/chez/seed/image.ss, then commit the refreshed files.
