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.

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.

All 10 vector primitives now have :as type annotations on every parameter,
:returns types, and :doc strings. make-vector gains optional fill annotation;
vector uses :rest for its variadic args; vector-ref/set! document bounds error.

vector-ref and vector-set! now raise Eval_error on out-of-bounds index instead of
an OCaml array exception. vector-copy accepts optional start and end parameters for
slicing (R7RS §6.8). spec/primitives.sx doc updated to reflect slice params.

Plans + briefings for four new language loops, each with a delcc/JIT
showcase that the runtime already supports natively:
- common-lisp — conditions + restarts on delimited continuations
- apl — rank-polymorphic primitives + 6 operators on the JIT
- ruby — fibers as delcc, blocks/yield as escape continuations
- tcl — uplevel/upvar via first-class env chain, the Dodekalogue
Launcher scripts now spawn 12 windows (was 8).
Five new guest-language plans mirroring the js-on-sx / hs-loop pattern, each
with a phased roadmap (Progress log + Blockers), a self-contained agent
briefing for respawning a long-lived loop, and a shared restore-all.sh that
snapshots state across all seven language loops.
Briefings bake in the lessons from today's stall debugging: never call
sx_build (600s watchdog), only touch lib/<lang>/** + own plan file, commit
every feature, update Progress log on each commit, route shared-file
issues to Blockers rather than fixing them.

40 clusters across 6 buckets. Bucket E is human-only (WebSocket,
Tokenizer-API, SourceInfo, WebWorker, fetch non-2xx). Agent loop
works A→B→C→D→F serially, one cluster per commit, aborts on
regression.

Initial commit of the lib/js/ tree and plans/ directory. A previous
session left template-string work in progress — 278/280 unit tests pass
(2 failing: tpl part-count off-by-one, escaped-backtick ident lookup).
test262-runner.py and scoreboard are placeholders (0/8 with 7 timeouts);
fixing the runner is the next queue item.
