Bytecode compiler now emits OP_PERFORM for (import ...) and compiles
(define-library ...) bodies. The VM stores the import request in
globals["__io_request"] and stops the run loop — no exceptions needed.
vm-execute-module returns a suspension dict, vm-resume-module continues.
Browser: sx_browser.ml detects suspension dicts from execute_module and
returns JS {suspended, op, request, resume} objects. The sx-platform.js
while loop handles cascading suspensions via handleImportSuspension.
13 modules load via .sxbc bytecode in 226ms (manifest-driven), both
islands hydrate, all handlers wired. 2650/2650 tests pass including
6 new vm-import-suspension tests.
Also: consolidated sx-platform-2.js → sx-platform.js, fixed
vm-execute-module missing code-from-value call, fixed bootstrap.py
protocol registry transpiler issues.

Boots the full WASM kernel (js_of_ocaml mode) + 24 .sxbc modules
into a happy-dom DOM environment. Provides helpers for SX eval,
DOM queries, island hydration, and click simulation.
Smoke test covers: kernel eval, DOM manipulation via SX, component
rendering, signals (reset!/swap!/computed), effects, and island
hydration with button rendering — 19/19 pass in ~2.5s.
Known limitation: reactive text nodes inside islands don't re-render
after click (signal updates but cek-reactive-text doesn't flush).
