Yogthos 192ef66e7e ns: accept vector reference clauses; add Compiler/specials 
Two general fixes shaken out by clojure/tools.macro.

- The ns macro now accepts a vector reference clause [:require …] / [:use …],
  not just the list form (:require …). Clojure dispatches on (first clause) and
  accepts both; jolt silently dropped vector clauses, so a ns written with them
  loaded with nothing required/used (tools.macro's test ns uses [:use …]).
- clojure.lang.Compiler/specials is now a static whose keys are the special-form
  symbols (matching Clojure 1.2/1.3). Macroexpansion tooling reads
  (keys Compiler/specials) to know which heads not to expand.

tools.macro itself isn't fully passing yet — its mexpand-all works, but the
macrolet/symbol-macrolet tests need letfn to macroexpand to letfn* (jolt models
letfn as a special form, not a macro over letfn*), so it stays off the list.

make test green (+1 corpus row, 0 new divergences), shakesmoke byte-identical.
One re-mint (the ns macro).

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.
