jolt/test/chez/_ioreader.janet
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.

# jolt-at0a (inc W) — reader-coupled io deferred from inc V (jolt-yyud):
# clojure.java.io/reader (a StringReader over slurp/string/char[]/File/path),
# char-array, File.toURL/.toURI (-> a java.net.URL jhost), slurp draining a
# StringReader, and with-open's __close seam over both jhost readers and plain
# :close maps. All Chez-native (host/chez/io.ss); no analyzer change. Reader/edn
# runtime read (clojure.edn/read over a PushbackReader) stays jolt-r8ku.
