Chez Phase 1 (increment 3j): assemble the clojure.core prelude, -e-capable jolt-chez

Browse source 
Emit every non-macro clojure.core form through the live analyzer -> Chez emit
pipeline as a def-var! prelude (prelude mode, tier dependency order), load it
before a user expression, and you get an -e-capable jolt-chez: analysis on Janet,
execution on Chez. driver/emit-core-prelude assembles it (each form behind a
silent load guard so the Phase-2 multimethod forms don't break the rest);
bin/jolt-chez is the -e CLI, caching the prelude on disk keyed by source hash.

run-corpus-prelude.janet is the full parity gate this opens, the prelude-backed
sibling of run-corpus-chez. First baseline: 1220/2497 evaluated cases pass, 0 new
divergences (10 allowlisted: dynamic vars, class names, eval-order — deferred
Phase 2). The rest is the punch-list: ~360 emit-fail (real host interop, out of
the analyzer subset) and ~900 runtime crashes, mostly core fns calling
host-coupled seed natives with no Chez shim yet (str/format/vec, transients).
Follow-ups jolt-t6cr/kl2l/q3w8/9ls5.

Two shims landed to get the prelude to load and run. atoms.ss: atom/deref/swap!/
reset! (+ the compare/vals kernel) — needed at load time for
global-hierarchy = (atom (make-hierarchy)). predicates.ss: the type predicates +
name/namespace/boolean the overlay assumes are seed natives, matching the seed's
strict semantics. post-prelude.ss re-asserts char?/atom? after the prelude: the
overlay implements those by reading :jolt/type, which is false for Chez-native
chars/atoms, so its def-var! would clobber the correct native versions.

Per-case Scheme files are PID-unique so a foreground -e never reads a half-written
file while the gate runs.

;; type predicates + simple accessors (jolt-9ziu) — host-coupled seed natives.

;; These are seed primitives (not clojure.core overlay fns), so they're never
;; def-var!'d by the assembled prelude; the Chez host must provide them. Semantics
;; match the Janet seed (src/jolt/core_types.janet): map?/vector?/set? are STRICT
;; over the persistent-collection records, seq? is true only for real sequences,
;; coll? is the union. Records (shape-recs) are Phase 2, so the record arms of the
;; seed predicates are simply absent here for now.
