Source the conformance corpus from JVM Clojure; retire the prelude gate

Browse source 
corpus.edn :expected is now the value reference JVM Clojure produces, set by the
new test/conformance/regen-corpus.clj (one JVM process, per-row thread watchdog).
167 rows moved to the JVM value: ratios (/ 1 2)=>1/2, doubles (double 3)=>3.0,
shared-heap concurrency (the future/pmap/agent cases), clojure.math doubles. The
JVM is the spec; jolt is measured against it.

known-divergences.edn shrinks to the rows whose JVM value is an opaque host object
that can't round-trip to source (Java arrays, transients, atoms, beans, proxies,
chunks all print as #object[..@addr]) plus (fn* foo) and a few racy concurrency
cases (:flaky). The zero-janet gate's allowlist becomes the set of host gaps vs the
JVM spec (no Class/array/BigDecimal, :jolt reader, jolt's own printing).

Math/clojure.math sqrt/pow/floor/trig now return doubles (Chez returns exact for
exact args, e.g. (sqrt 9)=>3); JVM always returns a double.

extract-corpus.janet no longer writes corpus.edn unless asked (the test runner
imported it and was silently overwriting the JVM corpus with the spec sources'
placeholder answers). The prelude parity gate is deleted — the zero-janet spine +
certify.clj are the oracles.

zero-janet 2678 (0 new divergences), certify 0 new / 0 stale, emit-test 330/330.

# Phase 0b — extract the spec corpus into a host-neutral contract file.

# corpus.edn :expected is sourced from reference JVM Clojure by
# test/conformance/regen-corpus.clj — this extractor's :expected column is a
# placeholder. Use it to (re)derive the case list when adding spec rows, then run
# regen-corpus.clj to fill :expected from the JVM. Do not commit its raw output.

# Parses every test/spec/*.janet as DATA (no eval), pulls each

# is valid BOTH as EDN (a future Chez-jolt runner reads it) and as Janet data
