lua-force: force promises (delay thunk protocol)
Fix lua-len: replace has? (unavailable in sx_server) with nil-check.
Fix string.byte: use string->list to get char type, not nth on string.
Fix string.char: truncate float codes before integer->char.

Type predicates, arithmetic, chars (inline α/digit/case),
format, gensym, values, sets, radix, list utilities.
cl-empty? guards all list traversal against () vs nil in sx_server.
Load spec/stdlib.sx in test.sh to expose format.
Fix lib/r7rs.sx number->string to use (= (len r) 0) not (nil? r).

28 tests, passes on both JS and OCaml.
- spec/stdlib.sx: pure SX format function
- spec/primitives.sx: format primitive declaration
- lib/r7rs.sx: fix number->string to support optional radix arg
- hosts/ocaml: add format-decimal primitive, load stdlib.sx in test runner
- hosts/javascript: load stdlib.sx in test runner

Adds 9 regexp primitives to stdlib.regexp. OCaml: SxRegexp(src,flags,Re.re)
using Re.Pcre; $&/$1 capture expansion in replace. JS: native RegExp
with SxRegexp wrapper; regexp-match returns {:match :start :end :groups}.
32 tests in test-regexp.sx, all pass on both hosts.

Adds 13 set primitives to stdlib.sets. OCaml: SxSet as (string,value)
Hashtbl keyed by inspect(val); JS: SxSet wrapping Map keyed by
write-to-string. Structural equality — (make-set '(1 2)) contains 1.
Includes union, intersection, difference, for-each, map.
33 tests in test-sets.sx, all pass on both JS and OCaml.

Adds read, write, display, newline, write-to-string, display-to-string
and current-*-port primitives to both JS and OCaml hosts.
JS: sxReadNormalize (#t/#f→true/false), sxReadConvert (()→nil),
sxEq array comparison, sxWriteVal symbol/keyword name fix,
readerMacroGet/readerMacroSet registry in parser platform.
OCaml: sx_write_val/sx_display_val helpers, read/write/display/newline
primitives on port types; parser extended for #t/#f and N/D rationals.
42 new tests (test-read-write.sx), all passing on JS and OCaml.

SxRational type in OCaml (Rational of int * int, stored reduced, denom>0)
and JS (SxRational class with _rational marker). n/d reader syntax in
spec/parser.sx. Arithmetic contagion: int op rational → rational, rational
op float → float. JS keeps int/int → float for CSS backward compatibility.
OCaml as_number + safe_eq extended for cross-type rational equality so
(= 2.5 5/2) → true. 62 tests in test-rationals.sx, all pass.
JS: 2232 passed. OCaml: 4532 passed (+11 vs pre-fix baseline).

Eof sentinel and Port{PortInput/PortOutput} in sx_types.ml. All 15 port
primitives in sx_primitives.ml. type_of/inspect updated. 39/39 port tests
pass (4532 total, +39, zero regressions).

Phase 14: port type + eof-object. Input ports track _pos cursor; output ports
accumulate _buffer. All 15 port primitives in spec/primitives.sx (stdlib.ports
module), platform.py (JS), and 39/39 tests in spec/tests/test-ports.sx.

gensym_counter ref + gensym/string->symbol/symbol->string/intern/symbol-interned?
primitives in sx_primitives.ml. Fix ListRef case in seq_to_list on both
sx_ref.ml and sx_primitives.ml. 19 new tests in test-gensym.sx.
OCaml 4450/1080, JS 2205/2497, zero regressions.

- seq-to-list: coerce list/vector/string/nil to list
- ho-setup-dispatch: apply seq-to-list to all collection args so map/filter/
reduce/for-each/some/every? work over vectors and strings natively
- sequence->list, sequence->vector, sequence-length, sequence-ref,
sequence-append: full polymorphic sequence helpers
- in-range: list-returning range generator (eager, works with all HO forms)
- Restore 3 accidentally-deleted make-cek-state/make-cek-value/make-cek-suspended
- Fix 8 shorthand define forms (transpiler requires long form)
- Add vector->list/list->vector to transpiler js-renames + platform aliases
- JS: 2137 passing (+28 vs HEAD baseline)

25 tests pass on both JS and OCaml hosts. Uses dict marker
{:_values true :_list [...]} for 0/2+ values; 1 value passes
through directly. step-sf-define extended to desugar shorthand
(define (name params) body) forms on both hosts.
