Three-part fix for hs-upstream-core/asyncError test 2/2:
1. runtime.sx hs-win-call: when an async call returns a rejected promise,
store the error value in window.__hs_async_error (side-channel) and
raise the sentinel "__hs_async_error__" so the value survives the
raise boundary intact.
2. compiler.sx catch clause: inject `(let ((var (host-hs-normalize-exc var))) ...)`
around the catch body so the sentinel gets swapped for the real error
object before user code runs. Uses let (not set!) so shadowing works
correctly for guard catch variables.
3. tests/hs-run-filtered.js:
- host-promise-state wraps JS Error objects as plain {message:...} dicts
before they cross the WASM boundary (Error.toString() was producing
"Error: boom" strings instead of accessible objects)
- host-hs-normalize-exc native retrieves the side-channel value when
the sentinel arrives in a catch variable
- host-get coercion restricted to El instances — plain JS objects with
a "value" key were being stringified to "[object Object]"

Add (when (not (nil? target)) ...) guards after every hs-null-raise!
call in both the compiler and runtime so execution stops cleanly when
a DOM element is not found, instead of continuing into a JS operation
on null that takes ~34 seconds to propagate.
Compiler: emit-set dot/poss, emit-inc/dec poss case, remove-element,
remove-attr, add-styles all now wrap the action after hs-null-raise!
in a nil guard.
Runtime: hs-toggle-class!, hs-toggle-between!, hs-dispatch!,
hs-set-attr!, hs-toggle-attr!, hs-set-inner-html!, hs-put!,
hs-transition all guarded — hs-settle and hs-measure already were.

lib/js/stdlib.sx (36 forms):
- Bitwise ops (js-bitand/bitor/bitxor/lshift/rshift/urshift/bitnot) use
truncate instead of js-num-to-int (which calls integer /0 and crashes).
- Map class: dict-backed list-of-pairs with linear-scan find, mutable via
dict-set!; js-map-new/get/set!/has/delete!/clear/keys/vals/entries/for-each.
- Set class: backed by SX make-set primitive; set-member?/set-add!/set-remove!
all take (set item) argument order — fixed from (item set) which threw.
- RegExp: callable lambda wrapping js-regex-new (not a dict, so directly callable).
- Wires Map/Set/RegExp into js-global.
lib/js/test.sh: epochs 6000-6032 (25 tests) — all pass.
Result: 492/585 tests pass (was 466/560 before this phase).

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)

parser.sx: detect bare ident "initial" after "to" in parse-one-transition,
emit string sentinel instead of (ref "initial") which evaluated to nil.
runtime.sx: hs-transition stores pre-first-transition style as
data-hs-init-{prop}; restores it when value=="initial".
Also commits E37 tokenizer and E40 fetch test implementations that
accumulated in the working tree but weren't staged in prior commits.

Extends match-pattern in spec/evaluator.sx with an ADT case: when the
pattern is (CtorName var...) and the value is an ADT dict (:_adt true),
check :_ctor matches, arity matches, then recursively bind field patterns.
Supports nested patterns, wildcard _, variable binding, and zero-arg ctors.
Changes step-sf-match to route no-clause errors through raise-eval-frame
instead of direct error, allowing guard to catch non-exhaustive matches.
40/40 ADT tests pass (20 define-type + 20 match). Zero regressions.

OCaml: StringBuffer of Buffer.t in sx_types.ml; 5 primitives in
sx_primitives.ml (make-string-buffer, string-buffer?, string-buffer-append!,
string-buffer->string, string-buffer-length); inspect case added.
JS: SxStringBuffer with array+join backend; _string_buffer marker for
typeOf dispatch and dict? exclusion (also excludes _vector from dict?).
spec/primitives.sx: 5 define-primitive entries.
17/17 tests pass on both OCaml and JS.
