Fixed three fundamental issues:
1. cek-try arg passing: handler was called with raw string instead of
(List [String msg]), causing "lambda expects 1 args, got N" errors
2. Silent island hydration failures: hydrate-island now wraps body
render in cek-try, displaying red error box with stack trace instead
of empty div. No more silent failures.
3. swap! thunk leak: apply result wasn't trampolined, storing thunks
as signal values instead of evaluated results
Also fixed: assert= uses = instead of equal? for value comparison,
assert-signal-value uses deref instead of signal-value, HTML entity
decoding in script tag test source via host-call replaceAll.
Temperature converter demo page now shows live test results:
✓ initial celsius is 20
✓ computed fahrenheit = celsius * 1.8 + 32
✓ +5 increments celsius
✓ fahrenheit updates on celsius change
✓ multiple clicks accumulate
1116/1116 OCaml tests pass.

Temperature converter tests (6 tests): initial value, computed
fahrenheit derivation, +5/-5 click handlers, reactive propagation,
multiple click accumulation.
New components:
- sx/sx/reactive-islands/test-runner.sx — reusable defisland that
parses test source, runs defsuite/deftest forms via cek-eval, and
displays pass/fail results with re-run button
- sx/sx/reactive-islands/test-temperature.sx — standalone test file
Added cek-try primitive to both browser (sx_browser.ml) and server
(sx_server.ml) for safe test execution with error catching.
Browser bundle now includes harness files (harness.sx,
harness-reactive.sx, harness-web.sx) for inline test execution.
Known: SSR renders test runner body instead of placeholder, causing
arity error on complex str expressions. Needs island SSR handling fix.
