Track halt mode via __hs-no-stop flag; skip stopPropagation when
handler raised hs-halt-default (from 'halt default'). All other
halt variants (halt, halt the event, halt bubbling) unchanged.

- compiler: wrap catch body in nested guard so (raise e) inside a
catch handler defers the re-raise until after the guard exits,
avoiding the handler-stays-active infinite loop
- generator: MANUAL_TEST_BODIES for rethrown/uncaught exception events,
can-pick-detail/event-property, bootstrap bootstraps; remove from
skip-list; regenerate behavioral spec

collect-pairs! in parse-add-cmd now skips the semicolon op token
between CSS properties, so add {color: red; font-family: monospace}
compiles to two dom-set-style calls instead of three malformed ones.

Parser: parse-cmd-list now skips a leading 'then' token so that
'on click from #bar then add .clicked' compiles correctly instead
of producing nil as the body.
Bootstrap tests: fix two broken tests whose assertions were
incomplete or contradictory:
- "cleanup removes event listeners" — deactivate + re-click to
verify listener is gone
- "reinitializes if script attribute changes" — actually change
the _ attribute before re-activating and re-clicking

SX uses nil (not null) as the null value; null is an undefined symbol
that caused _run-test-thunk to throw before the guard could catch it.
Also adds globalFunction mock for call-cluster tests.

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.

Implements hs-tokens-of, hs-stream-token, hs-stream-consume,
hs-stream-has-more, hs-token-type, hs-token-value, hs-token-op?,
hs-raw->api-token, hs-eof-sentinel in runtime.sx.
Tokenizer emits whitespace tokens after the first content token;
stream functions skip them for look-ahead and consume. Parser
filters whitespace tokens at hs-parse entry. Dot/hash after close
brackets split into PERIOD/POUND + IDENTIFIER. Template escape \$
produces literal $.

Merge c36fd5b2 stripped the source-info dict unwrapping from hs-to-sx
(the (let ((ast (if (and (dict? ast) (:hs-ast)) ...) wrapper) and also
introduced E37 tokenizer whitespace-token changes that broke the parser.
Reverts tokenizer/runtime to pre-E37 HEAD~1 state, restores hs-to-sx
with AST unwrapping from 61c9697f, and adds back the hs-id= dispatch
clause. Baseline: 178/195.

Hand-write sf_define_type in bootstrap.py FIXUPS (skipped from transpile
because the spec uses &rest params and empty-dict literals the transpiler
can't emit). Registers define-type via register_special_form. Adds
step_limit/step_count to PREAMBLE (referenced by sx_vm.ml/run_tests.ml).
172 assertions pass (test-adt). Full suite: 4280/1080 (was 4243/1117).

Add hs-raw->api-token, hs-eof-sentinel, hs-api-list, hs-tokens-of,
hs-stream-token, hs-stream-consume, hs-stream-has-more, hs-token-type,
hs-token-value, hs-token-op? to runtime. Fix tokenizer to emit whitespace
tokens and handle dot/hash after closing brackets. Fix hs-tokens-of to
accept bare :template keyword flag via &rest args + some() check.
Remaining failure (string interpolation isnt surprising) requires full
DOM activation infrastructure.

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.

Lost when resolving E37 reformat conflicts — re-added:
- hs-id= function in runtime.sx (JS === for elements, = for scalars)
- hs-id= dispatch in compiler.sx (after = clause)
Parser already uses hs-id= for != operator (unchanged).
- hs-id= uses JS === for DOM elements (hs-ref-eq), = for scalars
- != operator now uses hs-id= for structural correctness
- compound tag[attr=val] selector matching in test runner
- dom-query-all replaces host-call querySelectorAll
- DOM tree structure corrected in 4 generated tests (elements were
appended to wrong parents)
17 tests written inline with the implementation step. All 17 pass
on OCaml and JS. Phase 5 fully done as d98b5fa2.

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.

10 new tests: state field transitions (ready/suspended/dead), yield from
nested helper function, initial resume arg ignored by ready coroutine,
mutable closure state via dict-set!, complex yield values (list/dict),
round-robin scheduling, factory creates independent coroutines, resuming
non-coroutine raises error.
27/27 pass on both OCaml and JS.

All CEK primitives (cek-step-loop/cek-resume/make-cek-state/cek-suspended?/
cek-io-request/cek-terminal?/cek-value) were already registered in sx-browser.js.
Root cause of test failure: (import (sx coroutines)) creates an io-suspended
state when the library isn't pre-loaded; overridden cekRun throws on suspension.
Fix: pre-load spec/signals.sx + spec/coroutines.sx before test files run.
17/17 coroutine tests pass in JS. 1965/2500 total (+25 vs 1940 baseline),
zero new failures.

No native SxCoroutine type needed. dict-based coroutine identity +
cek-step-loop/cek-resume/perform/make-cek-state primitives already in
run_tests.ml fully implement the coroutine contract. 284/284 pass
(coroutines+vectors+numeric-tower+dynamic-wind), zero regressions.

spec/coroutines.sx: define-library with make-coroutine, coroutine-resume,
coroutine-yield, coroutine?, coroutine-alive?. Built on existing perform/
cek-step-loop/cek-resume suspension machinery.
spec/tests/test-coroutines.sx: 17 tests — multi-yield, final return,
arg passthrough, alive? predicate, nested coroutines, recursive iteration,
independent coroutine interleaving.
Key: coroutine body must use (define loop (fn…)) not named let — named let
transpiles to cek_call→cek_run which rejects IO suspension. All 17/17 pass.

Fix compiler: (block-literal () body) was emitting bare body instead of
(fn () body). Now always wraps in fn regardless of param count.
Generator: MANUAL_TEST_BODIES for all 4 blockLiteral tests using apply
and SX map rather than JS array.map.

Generator emit_eval translates arr.reduce/map/filter to SX primitives
so SX list args work. host-call-fn sxToJs converts SX lists to native
JS arrays for native JS function calls. Fixes functionCalls
"can pass an array literal as an argument".

Parser: parse-js-block extracts raw JS source by character positions.
Compiler: js-block AST → hs-js-exec call, stores result in it.
Runtime: hs-js-exec creates JS Function, handles promise rejection.
Test runner: host-new-function/host-promise-state natives + promise monkey-patch.

hs-make-object no longer appends _order to every HS object literal.
Generator emit_eval now uses assert-equal (equal?) for dict-containing
expected values instead of assert= (= reference equality).
Together these fix arrayLiteral "arrays containing objects work".

- transpiler.sx: after-thunk→cf_f, winders-len→cf_extra,

empty .class compiled (empty-target (query ".class")) to
(hs-empty-target! (hs-query-first ".class")) via hs-to-sx — only
emptying the first match. Fix: detect (query ...) target in the
empty-target compiler case and emit (for-each (fn (_el)
(hs-empty-target! _el)) (hs-query-all sel)) instead, mirroring the
add-class pattern. Suite hs-upstream-empty: 12/13 → 13/13.
Smoke 0-195: 175/195 unchanged.

${}{"val"} pattern in add {prop: ${}{"val"}} uses two consecutive brace
groups: empty ${} followed by {"val"} for the actual expression. The prior
fix called parse-expr when already at the brace-close of the empty group,
returning nil. New fix: detect empty ${} (brace-open then brace-close),
skip the close, then read the actual value from the following {…} block.
Also handles non-empty ${expr} directly as before.
Suite hs-upstream-add: 17/19 → 18/19. Smoke 0-195: 174/195 → 175/195.
