component-source from data/helpers.sx was overriding the native
OCaml version. The SX version calls env-get with wrong arity (1 arg
vs required 2), producing empty source. Re-bind the native version
in SSR overrides after file loading.
Note: source code still not visible because highlight function
returns empty — separate issue in the aser rendering pipeline.
Also adds:
- spec/tests/test-reactive-islands.sx — 22 SX-native tests for all
14 reactive island demos (render + signal logic + DOM)
- tests/node/run-sx-tests.js — Node runner for SX test files
- tests/node/test-reactive-islands.js — 39 Node/happy-dom tests
