Yogthos 424ce75cf6 mutable deftype fields: (set! field val) in a method
deftype fields tagged ^:unsynchronized-mutable / ^:volatile-mutable can now be
reassigned in place from a method, as on the JVM. A jrec stores fields as cons
cells, so a new jolt-set-field! mutates the pair with set-cdr!. The deftype macro
rewrites (set! mutable-field v) in a method body to (set! (.-field inst) v), and
the analyzer compiles a (set! (.-field obj) v) target to jolt-set-field! — so
both the rewritten symbol form and an explicit interop (set! (.-root this) v) go
through one path. Field reads remain a snapshot at method entry, which is correct
for the universal read-then-set pattern (a repeated set! of the same field in one
call would read the entry value).

Closes the set!-of-local SCI failures: SCI load 202 -> 205/218.

;; run-sci.ss — SCI conformance: load borkdude/sci's own source (vendor/sci) through
;; joltc and require its forms to compile+eval. A real-world Clojure-compatibility
;; stress test. Pure Chez, no Janet. Floor-gated like the corpus: a regression below
;; the floor (or the count today, 205/218) fails. Raise the floor as host gaps close
;; (the tail is genuine gaps — set! on vars, some macro/def shapes).
;;
;; chez --script host/chez/run-sci.ss
;; JOLT_SCI_FLOOR=N override the floor (default 205)
