The unit tests in test/chez/_*.janet now drive bin/joltc (the zero-Janet
spine) and judge against baked expected values instead of a live build/jolt
run. Ten of them captured the oracle from build/jolt per case; their values
are now literals (one env-dependent javastatic case became a predicate so it
stays portable). The rest already had literal expecteds with a redundant
build/jolt sanity check, now dropped.
Retire emit-test/emit-parity/reader-parity: they compared the Chez/Clojure
path against a live Janet evaluation, emitter, or reader. That migration check
is done, and run-corpus-zero-janet (Chez analyzer vs the JVM corpus) plus
certify.clj cover correctness now.
Rewrite the README for the current zero-Janet gate.

Bring the clojure.string namespace up on Chez so aliased refs like s/split,
s/upper-case, s/join, s/replace resolve and run.
Three pieces. (1) The Chez AOT driver analyzes the whole user form before any
require runs, so a (require '[clojure.string :as s]) never registered the
alias in time; eval-e-with-prelude now recursively pre-evals require/use forms
against the ctx, which loads the aliased ns and registers the alias so the
analyzer resolves s/X to a clojure.string var. (2) emit-core-prelude emits
stdlib namespaces (clojure.string) as their own def-var! tier through the same
analyze->emit pipeline, so the runtime var-deref resolves. (3) natives-str.ss
def-var!s the str-* primitives clojure.string.clj is written over (upper/lower/
trim/triml/trimr/find/reverse-b/join/split/replace/replace-all), plus no-op
require/use. Regex split keeps interior empties and honors the limit (ported
the seed re-split); regex replace does $N backref expansion and fn replacement
(ported replacement-for). new RT/clj files added to the prelude fingerprint.
Corpus prelude floor 2026 -> 2078 (+52), 0 new divergences. _strns 28/28 vs
build/jolt. Four previously-CRASHING cases now emit+run and surface pre-existing
gaps (read-line vector eval-order x3, instance? clojure.lang.Atom) — allowlisted
with notes. full jpm test + conformance x3 green.
