Chez inc 3l: transient collection RT shims

Browse source 
transient/persistent!/conj!/assoc!/dissoc!/disj!/pop! as copy-on-write over the
persistent collections (host/chez/transients.ss) — each op rebuilds the persistent
coll (no in-place perf) but the semantics match, so into/frequencies/group-by work.
Adds persistent disj over pset-disj. get/count/contains? are redefined to see
through a transient (frequencies and group-by both do (get tm k) on a transient
map); vector? on a transient vector is false, which group-by relies on.

Prelude parity 1326 -> 1382/2497, 0 new divergences. emit-test exercises the direct
transient ops via run-prelude and the overlay users (frequencies/group-by/into)
end-to-end through the bin/jolt-chez -e binary.

# Regression floor (inc 3j baseline): raise as runtime gaps close, like the probe
# reach-floor and the suite baseline. The gate fails if parity drops below it, or
# on any NEW (un-allowlisted) divergence — a real Chez correctness regression.
# Full-corpus baseline: inc 3j 1220/2497; inc 3k (converters) 1326. Strided runs
# scale the floor down.
