host-set! now stringifies values for innerHTML/textContent properties.
host-get returns string for innerHTML/textContent/value/className.
Fixes "Expected X, got X" type mismatch failures where number 22 != string "22".
437/831 (52.6%), +20 tests from stringify fix.

- sx_vm.ml: VM timeout now compares vm_insn_count > step_limit instead of
unconditionally throwing after 65536 instructions when limit > 0
- sx_browser.ml: Expose setStepLimit/resetStepCount APIs on SxKernel;
callFn now returns {__sx_error, message} on Eval_error instead of null
- compiler.sx: emit-set handles array-index targets (host-set! instead of
nth) and 'of' property chains (dom-set-prop with chain navigation)
- hs-run-fast.js: New Node.js test runner with step-limit timeouts,
SX-level guard for error detection, insertAdjacentHTML mock,
range selection (HS_START/HS_END), wall-clock timeout in driveAsync
- hs-debug-test.js: Single-test debugger with DOM state inspection
- hs-verify.js: Assertion verification (proves pass/fail detection works)
Test results: 415/831 (50%), up from 408/831 (49%) baseline.
Fixes: set my style["color"], set X of Y, put at end of (insertAdjacentHTML).
