Updates the pre-bundled HS tokenizer/parser/compiler/runtime/integration
sx + sxbc pairs plus module-manifest.json in shared/static/wasm/sx/,
matching the current HS source after recent patches (call command,
event destructuring, halt/append, break/continue, CSS block syntax, etc.).

The htmx-boot-subtree! function (defined in lib/hyperscript/htmx.sx)
was never loaded in the browser because hs-htmx.sx wasn't in the
bundle or compile-modules lists. Added to:
- bundle.sh: copy htmx.sx as hs-htmx.sx to dist
- compile-modules.js: compile to hs-htmx.sxbc, add to deps and lazy list
This was the root cause of "Load Content" button not working —
hx-* attributes were never activated because htmx-boot-subtree!
was undefined.

Root cause: sx_browser.ml registered all HTML tags (a, b, i, p, s, u, g, etc.)
as custom special forms. The evaluator's step_eval_list checked custom special
forms BEFORE checking local env bindings. So (let ((a (fn () 42))) (a))
matched the HTML tag <a> instead of calling the local function a.
Fix: skip custom special forms AND render-check when the symbol is bound in
the local env. Added (not (env-has? env name)) guard to both checks in
step-eval-list (spec/evaluator.sx and transpiled sx_ref.ml).
This was the root cause of "[sx] resume: Not callable: nil" — after hs-wait
resumed, calling letrec-bound functions like wait-boot (which is not an HTML
tag) worked, but any function whose name collided with an HTML tag failed.

Root cause: sx_insert_near placed break-lines-greedy, pretext-position-line,
pretext-layout-lines OUTSIDE the define-library begin block. The bytecode
compiler only compiles forms inside begin as STORE_GLOBAL — forms outside
are invisible to the browser VM.
Fix: moved all function definitions inside (begin ...) of (define-library).
Bytecode now includes all 17 functions (11K compiled, was 9K).
Browser load-sxbc: simplified VmSuspended handling — just catch and
continue, since STORE_GLOBAL ops already ran before the import OP_PERFORM.
sync_vm_to_env copies them to global_env.
Island now calls break-lines and pretext-layout-lines from bytecode-compiled
library — runs on VM, not CEK interpreter.

- text-layout.sx added to WASM bytecode pipeline (9K compiled)
- Fix multi-list map calls (map-indexed + nth instead of map fn list1 list2)
- pretext-layout-lines and pretext-position-line moved to library exports
- Browser load-sxbc: handle VmSuspended for import, copy library exports
to global_env after module load (define-library export fix)
- compile-modules.js: text-layout in SOURCE_MAP, FILES, and entry deps
- Island uses library functions (break-lines, pretext-layout-lines)
instead of inlining — runs on bytecode VM when exports resolve
Known issue: define-library exports don't propagate to browser global env
yet. The load-sxbc import suspension handler resumes correctly but
bind_import_set doesn't fire. Needs deeper investigation into how the
WASM kernel's define-library registers exports vs how other libraries
(adapter-html, tw) make their exports available.

Streaming chunked transfer with shell-first suspense and resolve scripts.
Hyperscript parser/compiler/runtime expanded for conformance. WASM static
assets added to OCaml host. Playwright streaming and page-level test suites.

Scope-based cursor walks the existing SSR DOM during island hydration
instead of creating new elements and calling replaceChildren. The
hydration scope (sx-hydrating) propagates through define-library via
scope-push!/peek/pop!, solving the env isolation that broke the
previous set!-based approach.
Changes:
- adapter-dom.sx: hydrating?, hydrate-next-node, hydrate-enter/exit-element
helpers. render-to-dom reuses text nodes. render-dom-element reuses
elements by tag match, skips dom-append. reactive-text/cek-reactive-text
reuse existing text nodes. render-dom-fragment/lake/marsh skip append.
dispatch-render-form (if/when/cond) injects markers into existing DOM.
- boot.sx: hydrate-island pushes cursor scope, skips replaceChildren.
On mismatch error, falls back to full re-render.
Result: zero DOM destruction, zero visual flash, event listeners
attached to original SSR elements. Stepper clicks verified working.

- sx_browser.ml: restore VmSuspended handler in api_call_fn with
make_js_callFn_suspension for IO suspension chains (wait, fetch)
- runtime.sx: delete host-get stub that shadowed platform native —
hs-toggle-class! now uses real FFI host-get for classList access
All three live demo examples work:
Toggle Color — classList.toggle on click
Bounce — add .animate-bounce, wait 1s suspend, remove
Count Clicks — increment @data-count, put into innerHTML
4/4 bytecode regression tests pass (was 0/4 without VmSuspended).

Three bugs fixed:
1. host-get in sx-platform.js: return true for function-valued properties
so dom-get-attr/dom-set-attr guards pass (functions can't cross WASM boundary)
2. hs-runtime.sx: renamed host-get→hs-host-get and dom-query→hs-dom-query to
stop shadowing platform natives when loaded as .sx source
3. compile-modules.js: HS dependency chain (integration→runtime→compiler→parser→tokenizer)
so lazy loading pulls in all deps. Non-library modules load as .sx source
for CEK env visibility.
Result: 8/8 elements activate, hs-on attaches listeners. Click handler needs
IO suspension support (VmSuspended in sx_browser.ml) to fire — next step.

- orchestration.sx: add hs-boot-subtree! call to process-elements
- integration.sx: remove load-library! calls (browser loads via manifest)
- sx_vm.ml: add __resolve-symbol hook to OP_GLOBAL_GET for lazy loading
- compile-modules.js: add HS modules as lazy_deps in manifest
HS compilation works in browser (tokenize→parse→compile verified).
Activation pipeline partially working — hs-activate! needs debugging
(dom-get-data/dom-set-data interaction with WASM host-get on functions).

Reset to last known-good state (908f4f80) where links, stepper, and
islands all work, then recovered all hyperscript implementation,
conformance tests, behavioral tests, Playwright specs, site sandbox,
IO-aware server loading, and upstream test suite from f271c88a.
Excludes runtime changes (VM resolve hook, VmSuspended browser handler,
sx_ref.ml guard recovery) that need careful re-integration.

All .sxbc recompiled with fixed sx_vm.ml. 32/32 WASM tests, 4/4
bytecode regression tests. hs-repeat-times correctly does 6 io-sleep
suspensions in bytecode mode.

When the VM or CEK hits an undefined symbol, it checks a symbol→library
index (built from manifest exports at boot), loads the library that
exports it, and returns the value. Execution continues as if the module
was always loaded. No import statements, no load-library! calls, no
Suspense boundaries — just call the function.
This is the same mechanism as IO suspension for data fetching. The
programmer doesn't distinguish between calling a local function and
calling one that needs its module fetched first. The runtime treats
code as just another resource.
Implementation:
- _symbol_resolve_hook in sx_types.ml — called by env_get_id (CEK path)
and vm_global_get (VM path) when a symbol isn't found
- Symbol→library index built from manifest exports in sx-platform.js
- __resolve-symbol native calls __sxLoadLibrary, module loads, symbol
appears in globals, execution resumes
- compile-modules.js extracts export lists into module-manifest.json
- Playground page demonstrates: (freeze-scope) triggers freeze.sxbc
download transparently on first use
2650/2650 tests pass.
