The sync aser-call in adapter-sx.sx didn't flatten list results from
map/filter in positional children — serialize(list) wrapped in parens
creating ((div ...) ...) which re-parses as an invalid call. Rewrote
aser-call from reduce to for-each (bootstrapper can't nest for-each
inside reduce lambdas) and added list flattening in both aser-call
and aser-fragment.
Also adds test-aser.sx (41 tests), render-sx platform function,
expanded test-render.sx (+7 map/filter children tests), and specs
async-eval-slot-inner in adapter-async.sx.

- 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
