SPEC_MODULES + SPEC_MODULE_ORDER for frames/cek in platform_js.py,
PLATFORM_CEK_JS + CEK_FIXUPS_JS constants, auto-inclusion in
run_js_sx.py, 70+ RENAMES in js.sx. Python: CEK always-include in
bootstrap_py.py, eval_expr/trampoline overridden to cek_run in
platform_py.py with _tree_walk_* preserved for test runners.

- Add page-helpers-demo page with defisland ~demo-client-runner (pure SX,
zero JS files) showing spec functions running on both server and client
- Fix _aser_component children serialization: flatten list results from map
instead of serialize(list) which wraps in parens creating ((div ...) ...)
that re-parses as invalid function call. Fixed in adapter-async.sx spec
and async_eval_ref.py
- Switch _eval_slot to use async_eval_ref.py when SX_USE_REF=1 (was
hardcoded to async_eval.py)
- Add Island type support to async_eval_ref.py: import, SSR rendering,
aser dispatch, thread-first, defisland in _ASER_FORMS
- Add server affinity check: components with :affinity :server expand
even when _expand_components is False
- Add diagnostic _aser_stack context to EvalError messages
- New spec files: adapter-async.sx, page-helpers.sx, platform_js.py
- Bootstrappers: page-helpers module support, performance.now() timing
- 0-arity lambda event handler fix in adapter-dom.sx

EvalError moved to types.py. All 27 files updated to import eval_expr,
trampoline, call_lambda, etc. directly from shared.sx.ref.sx_ref instead
of through the evaluator.py indirection layer. 320/320 spec tests pass.

- Fix qq-expand in eval.sx: use concat+list instead of append to prevent
nested lists from being flattened during quasiquote expansion
- Update append primitive to match spec ("if x is list, concatenate")
- Rebuild sx_ref.py with quasiquote fix
- Make relations.py self-contained: parse defrelation AST directly
without depending on the evaluator (25/25 tests pass)
- Replace hand-written JSEmitter with js.sx self-hosting bootstrapper
- Guard server-only tests in test-eval.sx with runtime check

SX-to-JavaScript translator written in SX itself. When executed by the
Python evaluator against the spec files, produces output identical to
the hand-written bootstrap_js.py JSEmitter.
- 1,382 lines, 61 defines
- 431/431 defines match across all 22 spec files (G0 == G1)
- 267 defines in the standard compilation, 151,763 bytes identical
- camelCase mangling, var declarations, function(){} syntax
- Self-tail-recursive optimization (zero-arg → while loops)
- JS-native statement patterns: d[k]=v, arr.push(x), f.name=x
