Yogthos 9a273e71cd Move the Chez test oracle off Janet
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.

# sequential? / seq? on lazy seqs (jolt-2o7x follow-up). The inc M fix made the
# native seq? var recognize a lazy-seq (re-def-var!, not just set!). sequential?
# is overlay (`(defn sequential? [x] (or (vector? x) (seq? x)))`), so it inherits
# the fix transitively; this pins that both predicates agree with the JVM oracle
# over every lazy-seq-producing form (and the native =/hash path via set!).
# Expectations are the JVM-canonical values.
